Polyurethane blocks are also incredibly resistant to severe impact and abrasion. This makes them ideal for heavy-duty projects, such as automotive and industrial equipment. They can withstand harsh impacts, abrasive surfaces, and other damages and wear and tear associated with daily and excessive use.

Mold Resistance

When it comes to mold, mildew, and fungi, polyurethane blocks are highly resistant. Most types of mold and fungi cannot penetrate the surface of these blocks, making them an ideal choice for projects that may be exposed to moisture or humidity. They are commonly used in outdoor furniture, decks, and patios since they aren’t susceptible to mold growth and require minimal maintenance.

Wide Resiliency Range

Another superior quality of polyurethane blocks is their resilience. Their ability to absorb shock, impact and vibration makes them an excellent choice for projects that require superior noise reduction or cushioning.

They also have remarkable elastic memory compared to other materials like plastic. They may change shape under a heavy load but always return to their original shape and size when the pressure is removed. Because of this, they are a go-to choice in making shock-absorbing products, such as vehicular and industrial parts.

Insulating Property

Whether heat, sound, or vibration, polyurethane blocks are excellent insulation materials. They are ideal for reducing noise, absorbing vibrations, and providing thermal insulation. These superior insulation properties help reduce energy costs, which is why most business buildings, houses, and other structures use them on their floors and walls to regulate temperature levels.

Polyurethane blocks are also good electrical insulators and can withstand high electrical currents and resist electricity transmission. Projects that require protection from electric shock or interference significantly benefit from these polymer materials.

Strong Bonding Properties

Polyurethane blocks have exceptional bonding properties. During processing, they can easily bond with other materials like metals, plastics, and wood. This makes them perfect for projects that require strong adhesion or a waterproof seal since they won’t easily separate from each other. They are commonly found in wheels, inserts, rollers, scrapers, squeegees, bumpers, and other rubber parts that need a robust and durable bond.

Size and Color Variations

Polyurethane blocks come in a wide range of custom sizes and colors. Whether you want small or large blocks, they can be made to the specific size you request. These polyurethanes are also highly customizable and can be dyed in any color you desire. This makes them ideal for projects that require unique shapes and colors to match your aesthetic needs.

How Are They Made?

Polyurethane blocks are produced by combining two chemical compounds: polyol and diisocyanate.

Polyol is a polymer made from different alcohol groups, while diisocyanate is an organic compound with two isocyanate groups. The chemical reaction of these two components leads to condensation, which forms polyurethane.

The production process of polyurethane blocks is relatively straightforward. It involves mixing the two compounds in a specialized machine, allowing them to react with each other, and making necessary adjustments to get the desired results. They can also be infused with different additives to improve their properties and make them more suitable for specific projects.

The mixture is then poured into a mold and left to cure. Once it solidifies, the block can be cut or shaped into various products for different purposes. The finished product then goes through quality control tests to ensure that it meets all performance specifications and industry standards.

Why is it Crucial to Get the Size Perfect for Polyurethane Blocks?

When it comes to polyurethane blocks, size does matter. The size of the blocks affects the weight and performance of the polyurethane, which are crucial in choosing the suitable material for the job.

Smaller blocks may be more lightweight and ideal for projects needing a tight fit or waterproof seal. On the other hand, larger blocks are heavier and more capable of carrying heavier loads. They also provide more significant impact and shock resistance and are perfect for applications that require superior noise reduction or cushioning.

Different applications require different sizes of polyurethane blocks. Choosing the right size for your needs is critical to ensuring a successful and durable finished product.

Fortunately, polyurethane blocks come in custom sizes and shapes, allowing for maximum versatility in design. With the right size and formulation, polyurethane blocks can be a perfect fit for any project.

In 2023, the industrial machinery market has grown into a $545 billion dollar industry. Industries around the world rely on heavy manufacturing and industrial equipment. However, due to their constant use and exposure to the elements, this equipment can sustain damage like abrasion and corrosion. These mechanical issues also put the workers, customers, and properties that interact with the equipment at risk.

There are a few methods like the application of rubber or metal-based bumpers that prevent breakage and prolong the life of these types of machinery. However, polyurethane bumpers are the most practical solution. Read on to know more about polyurethane bumpers, their benefits, and where you can get them.

What Are Urethane Bumpers?

Polyurethane or urethane bumpers are pads or knobs made from the urethane synthetic compound. Urethane has the elasticity of rubber. However, it has better compression characteristics compared to plastic alternatives such as rubber. It does not tear or bounce off easily. Moreover, unlike rubber which produces a foul and sometimes toxic scent, urethane is odorless.

Urethane also has incredible durability and longevity that is relative to metal. It can accommodate huge loads of pressure without breaking. It likewise does not leave marks on surfaces and items it comes in contact with. Urethane also produces significantly less noise compared to metal.

Urethane bumpers come in many shapes and sizes. Some are threaded while others are not. They can be customized and molded to fit your particular needs too.

Round urethane bumpers have a durable and solid interior and impact-resistant rubber-like exterior. They are usually threaded. The male bumpers have a rigid stud made of metal or steel while the female bumpers have molded-in steel hex. This facilitates ease of installation and detachment. Round bumpers are used to position, guard, and alight objects moving through automated locomotive equipment.

Rectangular urethane bumpers are often reinforced with metal plating. The additional reinforcement allows for greater load and pressure accommodation. These bumpers are ideal for securing and positioning heavy-duty objects and parts. Moreover, the under-treated holes in rectangular bumpers can house a mounting bolt, thus giving the bumpers more versatility.

There are also square bumpers. These urethane bumpers are excellent at mitigating impact and vibration. They can also endure high temperatures and offer the same versatility as round and rectangular bumpers.

These urethane bumper solutions are commonly used in manufacturing plants. However, they can be used in any industrial setting.

You’ll mostly see urethane bumpers lining the edges of conveyor belts. They align and position the products as they move from one area of the assembly line to the next. They likewise prevent the products and equipment from damaging each other by absorbing the impact of collisions.

Aside from conveyor belts, urethane bumpers are also used as shock absorbers or stoppers for hydraulic cylinders, electric components, pneumatic cylinders, navy hatches, and many more applications.

Why Are They Used?

Urethane bumpers are widely used in commercial and industrial spaces. While there are alternatives like rubber and metal bumpers, engineers and factory operators prefer polyurethane bumpers for their several benefits.


Urethane bumpers are more affordable than their metallic counterparts or other mechanical solutions. Despite being cheaper, these bumpers offer equal or even greater durability, reliability, and flexibility than pricier alternatives. Some polyurethane bumpers even come in pre-manufactured molds, thus eliminating the additional cost of molding

Improved Production Speed and Efficiency

Urethane bumpers improve manufacturing speed and efficiency by smoothly and safely guiding components through the production system. They also facilitate automation and streamline workload, allowing your workers to focus on more critical aspects of the production process.

Moreover, these bumper’s low acoustic profile will mitigate noise levels in your factory and make communication among your workers easier.

Robust Composition

Polyurethanes are extremely wear-resistant and are more durable than most plastics and PVC options. They don’t easily degrade from heat and solvent exposure. Their elasticity and strength likewise give them a higher damage threshold. These characteristics make polyurethane bumpers ideal for demanding industrial processes where machinery is constantly subjected to huge amounts of load and pressure.

Ease of Installation and Maintenance

Urethane bumpers are easy to install since the pads or knobs already have built-in fasteners or adhesives. Moreover, these are simple tools that do not use springs or other complicated mechanisms that require a tedious installation procedure. By having a simple design with no moving parts, it’s likewise easier to maintain urethane bumpers.

Oil and Chemical Resistance

While the oil manufacturing industry’s revenue growth has experienced a slight dip this year, it’s still safe to say that oil is here to stay. Whether it be coming from the products themselves or from equipment grease and lubricants, oil is a common substance in a lot of industrial plants.

Oil contamination is the cause of around 70% to 80% of all hydraulic and other machinery failures. Hence, polyurethane bumpers’ oil resistance is highly beneficial. These bumpers can also withstand prolonged chemical exposure without getting unstable or severely swollen.

Corrosion Resistance

Metallic equipment in factories is always at risk of corrosion. This can disrupt manufacturing operations, lead to exorbitant repair costs, and compromise product quality. Annually, corrosion costs the manufacturing and production industry a whopping $17.6 billion in damages and losses.

Fortunately, urethane bumpers are a cost-effective preventive solution to this problem. Urethane bumpers provide one of the best corrosion resistance on the market. They will protect not only your expensive machinery but also the items and parts that go through them.

Abrasion Resistance

Unlike other forms of elastomers or metals, urethane bumpers do not easily get worn or scraped. They retain their smooth and uncompromised texture even when subjected to low temperatures or other highly abrasive conditions. Hence, they are the perfect option to use in machinery like conveyor belts where components can constantly collide with the bumpers.

How Are They Made?

Polyurethane bumpers are made from expanded urethane synthetic compound or polyurethane resin. The microcellular composition of this material contains open and closed cells. This is what allows the buffer in each bumper to have high elasticity and impact resistance.

Generally, this material is placed on a low–cost mold that shapes the bumper to fit standard industrial machinery. The OEM slots or holes are made through water jetting.

Metallic support is then added, with some urethane bumpers even containing a steel safety chain for enhanced structural integrity.

For more demanding applications, custom urethane bumpers can be made. A more rigid stud can be used for a more reliable fastening mechanism. Mount accommodations can likewise be included. Even the color of the bumper can be changed depending on your preference.

We’ll show you how custom molding is done and how to ensure you get the most value out of your purchase.

How Can You Customize Urethane?

For most industries, customizing urethane parts is an excellent way to increase efficiency and bring products to the market quickly. In addition, it’s the ideal solution when durability, weight, and safety are highly regulated.

Usually, producing custom-molded urethane varies depending on your preferences and applications. To give you an overview, we discuss the process below.

Mold Creation or Tooling

Before we start the production process, we’ll create custom molds that match your exact shape and performance requirements. Here, a machinist will create a tool path based on your specific requirements. The tool path will produce a mold for the part that, when filled with urethane, will yield an extremely precise product. Urethane custom molds are often intricate as parts become more complex.

Mass Production

When the molds are ready, they enter the production room for custom molding and mass production. Here, the production team uses different prepolymers, curatives, and ratios to create formulations that are specific to the particular job. These specially formulated mixtures (or urethane resin) are generally hand-batched or processed in automated dispensers or centrifugal mixers, depending on the specifications of the parts.

In the production room, our team uses several forming and curing methods to meet the end-use needs of customers. Here are some techniques used in the industry.

Compression Molding

Using compression molding, liquid polyurethane or millable gum is placed into enclosed multiple plates. Then, two hardened steel plates sandwich the compound using a hydraulic press. The press exerts high pressure and heat, forcing the polyurethane to fill the shape of the closed mold for curing.

This method is usually more expensive than other molding processes, but it allows for a much higher-quality end product. With a more refined outcome, this process is ideal for casting polyurethane bushings, seals, and other critical parts. However, it can be more expensive than other methods.

Open-cast Molding

Open-mold products are formed by pouring liquid polyurethane into an open mold. After pouring, the process is followed by curing the mold in an oven or heated table. This process is a fairly affordable method that produces high-quality parts.

Centrifugal Molding

Also called spin casting, centrifugal molding is a process that creates lightweight yet strong custom urethane in a single shot. As the liquid polyurethane is spun inside the mold, a centrifugal force channels liquid to fill every part of the mold, creating one solid piece. The finished product is well-suited for smaller parts that need to be bubble-free.


In this process, the liquid urethane is pushed into a mold at high pressure using a molding press. The resin conforms to the mold and hardens, shaping the material into almost any desired shape. Ideal for making bulk pieces, this method is cost-efficient and reliable while still allowing for customization.

Trimming/Secondary Machining

Trimming is a crucial step in the production of custom polyurethane products. In this step, our team removes excess urethane and creates clean, finished products. In some instances, some parts may undergo secondary machining, depending on their end-use. The parts are returned to the machine shop, where they may be milled or ground.


Inspection is the final step before shipment to customers. In this step, end products are inspected for precision and quality. If a part fails our standards, we discard it and manufacture a new one.

Advantages of Using Polyurethane Seals

Besides durability and longevity, there are many reasons why you should utilize or switch to cast urethane seals. For more inspiration, take a look below!

Extremely Versatile

Urethane seals are extremely versatile. These seals can be used in various applications, from industrial to residential and commercial settings and processes. They are also critical components in the production of medical equipment, vehicles, machinery, and marine equipment. Seal manufacturers can produce varieties of tight tolerances and characteristics to suit almost any application.

Maximum Sealing Properties

If you’re looking for tight tolerance seals, products made of urethane can be the perfect option. Used in everything from automotive and aerospace industries to chemical processing, urethane seals boast minimal leakage, which makes them ideal for use in hydraulic systems. They can prevent leakage at high pressure while allowing enough room for expansion.

Hydraulic fluid under pressure easily overcomes inferior technology, especially when internal gaps and clearances aren’t tight. Urethane seals are designed to change shape under pressure, which allows them to form a tight seal without leakage. However, when the pressure relaxes, they return to their original shape.

Abrasion Resistant

Polyurethane seals are designed with tight tolerances to resist shearing and tearing, meaning they can withstand abrasion without losing their ability to function properly. They won’t break down or become less effective over time due to abrasion. Thus, they’re necessary for heavy-duty applications, where their ability to withstand high amounts of friction is crucial. They’re an ideal choice for any application that requires protection against abrasion due to their ability to withstand extreme weather conditions.

In addition, cast polyurethane seals are also easy to maintain, which makes them ideal for environments where there’s a high volume of foot traffic or other sources of dirt and grime.

Chemical Resistant

Urethane seals are one of the most chemically resistant materials available for use across multiple industries. They maintain stability even when exposed to oil, fuel, water, solvents, and other industrial chemicals.

Polyurethane seals are chemical resistant because they’re made of a synthetic material that can withstand chemicals and other substances. They don’t break down or corrode when exposed to acids and alkalis, and they even resist attack by many organic solvents. This makes them ideal for use in areas where chemicals are present, such as manufacturing plants, oil refineries, and chemical plants.


Known for their flexibility, polyurethane seals can be custom-molded to fit a variety of products and industrial processes. This means that you can get the exact fit you want for your product, whether it’s a small space or an unusually-shaped hole in your machinery.

The seals can be manufactured in various flexible and rigid shapes, with either smooth or textured surfaces. Custom urethane seals are also available in various hardnesses and thicknesses, depending on the application. No matter how complex your needs are, there are always polyurethane seals that will conform to your requirements!


While custom urethane seals are more expensive than traditional rubber or plastic seals, they can be cost-efficient when considering their durability and low maintenance. Simply put, polyurethane seals are more durable and less likely to fail than other types of industrial seals, which means they will last longer. If you want a product that doesn’t need consistent repair and replacement, using urethane seals could be cost-effective in the long run for your company.

Fast Turnaround Times

As a business, you want to bring your products to market as quickly as possible. Whether you need these seals for your products or on your machinery to maintain continued operation, urethane seals deliver a fast solution to minimize equipment downtime.

Withstand Extreme Conditions

Rubber and plastic seals can melt when exposed to high temperatures. However, that’s not the case for polyurethane shaft seals. They are designed to tolerate high temperatures and pressure, making them perfect for applications requiring extreme heat tolerances — like, for example, gaskets and seals for engines. Depending on their hardness (durometer rating), cast urethane products can tolerate heat up to 400℉.

In addition, custom polyurethane seals don’t break, even in cold climates. They can operate at high performance to temperatures as low as -80℉. In short, these seals have high resistance to cold cracking that rivals other seal materials.

Low Compression Set

One of the best benefits of urethane seals is their low compression set. Urethanes are known for this quality: they don’t lose their shape or size over time. This is because urethanes are resistant to changes in temperature and pressure, unlike other materials such as rubber or plastic. They’re ideal for applications where the seal must withstand a great deal of pressure, such as in hydraulic systems.

Engineers in the rubber and plastics industries are required to measure the hardness of rubber, plastic, and other materials. This is to understand the mechanical specifications of materials or prospective materials that are used to produce products. By using a shore hardness tester (shore durometer) or digital durometer, engineers can tell how well a material will perform under specific conditions.

With how significant they are, durometer hardness tests must be performed and recorded accurately. In this article, we will talk about everything that product teams and engineers need to know about durometer testing.

What is a Durometer?

In industrial settings, a durometer is used to measure a material’s hardness, including rubber, plastic, and foam. It’s important that companies can accurately determine the hardness of these materials to ensure their products meet safety standards and regulations. This is to ensure that products are not too hard, which can lead to damage or injury, or too soft and unable to perform the required functions.

What is a Durometer Used For?

As mentioned, there are several materials that a durometer is used to measure. The most common applications are those involving rubber, plastic, and foam.

  • Rubber: This can be anything from car ties, shoe heels, and seat belts to hoses, seals, and gaskets. Under ISO 7619-1:2010, a specific method is used to determine the indentation hardness of vulcanized or thermoplastic rubbers.
  • Plastics: Durometers are also used for measuring the hardness of rigid plastics such as polypropylene, PVC (polyvinyl chloride), and ABS (acrylonitrile butadiene styrene). It is necessary to measure the hardness of these materials to determine their suitability for particular applications.
  • Foam: The hardness of foam materials is often measured with a shore durometer. This can help companies determine the best material for products such as cushioning, car seats, and mattresses.

Other non-rubber, non-plastic materials are also tested with durometers, such as wood and paper. In addition to understanding their mechanical properties, it’s often necessary to measure the flatness of these materials as well.

Different Shore Hardness Scales

A hardness scale, or durometer scale, is used to assign numerical values to the materials that are being tested. The most common durometer shore hardness scales are Shore 00, Shore A, and Shore D. All these different shore hardness scales measure the same thing but use different ranges to determine the material hardness.

  • Shore 00 Hardness Scale: In hardness testing, Shore 00 hardness test is used to measure rubbers and gels that are very soft. This is typically used for materials that are too soft to be tested on the Shore A or D scale, and it measures a maximum of 100.
  • Shore A Hardness Scale: The Shore A scale is the most commonly used durometer. This durometer measures rubber, soft plastics, and other materials with a hardness range of 0-100. Semi-rigid plastics can also be measured using the same durometer scale.
  • Shore D Hardness Scale: Measuring the hardness of semi-rigid plastics, hard plastics, and hard rubbers is done using the Shore D durometer scale. It has a hardness range of 0-100 and is used for materials that are harder than what the Shore A durometer can measure.

By accurately measuring indentation hardness or the initial hardness of a material, engineers can make sure that their products meet the necessary safety and performance requirements. Regardless of the different hardness scales, having a durometer as part of your process will help ensure that products are designed, produced, and tested to meet specific standards.

How to Physically Measure a Material’s Hardness

Hardness measurements can also be performed manually. By using a Shore Hardness Gauge — a piece of equipment that looks like a round tire pressure gauge with a needle on a spring protruding from one end — engineers can manually measure the hardness of a material by pressing it against the surface. Once pressed, the needle will penetrate the surface and deflect until the material’s hardness is measured. A specific hardness measurement will be shown on the gauge’s dial.

How Does a Durometer Work?

Under different international standards, there are many different methods used to measure the hardness of materials. Under ASTM D2240 standard test method for rubber property, twelve types of rubber hardness measurement devices are used. This includes A, B, C, D, DO, E, O, OO, and, OOO. Using a standardized presser footer, the durometer is pressed onto the material and a reading is taken.

If a timed hardness is required, a digital durometer is used to press the material and measure the hardness. In this case, the hardness of the material is measured over a specific duration instead of just one time. Unlike the usual measurement, the material under the timed hardness test should have a minimum of 6.4mm thickness.

How Durometer Influences Material Selection

If you are involved in manufacturing, selecting the right materials is an important part of the product design process. Knowing the specific properties of a material and its durometer hardness can help inform which material works best for your application.

Using a durometer to measure a material’s hardness will give you an accurate view of how the material behaves under different conditions. This information allows you to compare materials and select the best option for your product.

For a better perspective, here are some of the ways durometer hardness affects material selection.

Durometer Hardness Indicates How Elastic a Material is

The durometer scale is a measure of the hardness of a material, with higher numbers indicating a harder material and lower numbers indicating a softer material. Elasticity is a measure of how much a material can stretch or deform under a load and then return to its original shape when the load is removed. Materials with higher durometer hardness are generally less elastic and more rigid, while materials with lower durometer hardness are more elastic and more flexible.

Hardness Affects Abrasion Resistance and Wearability

Abrasion resistance is the ability of a material to resist wear or damage caused by friction or rubbing. Materials with moderate durometer hardness (around 85A) generally have better abrasion resistance, as they are more resistant to deformation and wear. This makes them more suitable for use in applications where they may be subjected to high levels of friction, such as in the soles of shoes or on conveyor belts.

Material Hardness Determines How Much Force is Required to Deform it

The amount of force required to deform a material is known as its tensile strength. Materials with higher durometer hardness generally have higher tensile strength, meaning they are more resistant to deformation and require more force to stretch or bend them. This is important in applications where the material may be subjected to heavy loads or impacts, as it determines the material’s ability to withstand these forces without breaking or failing.

Durometer Data Can Help Determine the Safety and Performance of a Product

Durometer hardness is an important factor to consider when selecting materials for a product, as it can have a significant impact on the safety and performance of the product. For example, a material with higher durometer hardness may be more suitable for use in a structural component, as it will be able to withstand higher loads without deforming.

On the other hand, a material with lower durometer hardness may be more suitable for use in a gasket or seal, as it will be able to conform to irregular surfaces and provide a better seal.

Hardness Affects Mechanical Shock Resistance, Compression Set, Temperature Range, and More

In addition to the factors mentioned above, durometer hardness can also affect a material’s resistance to mechanical shock, its ability to maintain its shape under a load (known as compression set), and its temperature range. Materials with higher durometer hardness generally have better mechanical shock resistance, lower compression set, and wider temperature range, making them more suitable for use in demanding applications.

The Bottom Line

A durometer is useful to measure the hardness of a material, and it can tell us a lot about its properties and suitability for various applications, especially for rubbers and urethanes. Knowing the durometer of a material can help determine its ability to withstand friction, compression modulus measurements (for rubber), deformation, impacts, and temperature and mechanical shock resistance.

Winter is here. It’s time for multiple layers, hot chocolate, and, most importantly, moving ice and snow from various surfaces. For this task, you’ll use your snow plows to clear out packed ice or snow from your parkways and driveways. However, when was the last time you checked the snow plow cutting edges?

Snow plows with steel cutting edges or rubber edges may get the job done, but we’d like to propose a more cost-effective, durable, and noiseless alternative — polyurethane cutting edges.

With urethane-cutting edges mounted on your snow plow, grinding noises and surface damage will be things of the past. Most importantly, polyurethane cutting edges are more cost-effective than they appear, as they’re resilient to the wear and tear brought by the cold months. Look no further if you’re looking at cutting edges for snow pushers or plows that address many of your winter pain points. Choose polyurethane cutting edges instead of rubber or metal cutting edges.

Why? Grab a warm beverage, put away your shovel and salt, and read on.

What is a Polyurethane Plow Edge?

A polyurethane cutting edge is part of a snow plow cutting edge system. It’s an accessory mounted at the base of a plow’s steel cutting edge.

Polyurethane edges attach to a snow plow’s default edges in several ways, depending on their mounting instructions. The most common attachment method is by bolting the polyurethane edges on drill holes.

Using this method, a person attaching the poly cutting edge will bolt a new cutting edge through a drill hole. Attached this way, the poly cutting edge stays on the steel edge and remains secure even on rough surfaces.

A polyurethane cutting edge is smooth, making them plow blades that can eliminate driver fatigue. In addition, cutting edges consist of polyurethane with a low friction coefficient, unlike metal cutting edges.

The low friction coefficient is also an excellent feature for snow blowers, snow plows, and snow pushers meant for more delicate surfaces — like those in residential areas. They also bend on uneven surfaces, making them safe for the driver, the surface, and the snow plow or pusher.

Polyurethane cutting edges also have maximum abrasion resistance because of their specialized urethane formulation. This gives them an edge in long-term durability and structural integrity.

In short, polyurethane cutting edges are perfect for snow plows, pushers, and snow blowers. They are accessories that attach to default-issue steel edges and provide users with a cutting edge that boasts all the qualities of polyurethane.

How Are Polyurethane Plow Edges Built?

Polyurethane plow edges are the products of engineered molding and construction. Manufacturers will often make polyurethane cutting edges in pre-set batches. These batches of cutting edges come in uniform specifications.

A manufacturer uses predetermined specs as guidelines for creating blades made of polyurethane. The specs will cover everything from the plow blade widths to thicknesses.

Unlike steel cutting edges, polyurethane cutting edges are moldable. Their moldability makes them easy and economical to produce, especially after a manufacturer configures and determines specs like thickness and material.

Because a cutting-edge polyurethane manufacturer fulfills massive shipments, there’s little to no room for customization. For this reason, you will receive a urethane snow plow edge that may not be exactly what you want. At best, you’ll get a cutting edge that only closely resembles the specs you have in mind. After receiving the edges, you’ll have to cut them yourself and figure out how to attach them to your snow plow.

Luckily, some companies manufacture custom polyurethane plow blades. If you want cutting edges that meet your ideal specifications, call a manufacturer that incorporates your additional information dimensions. For customized polyurethane snow plow edges, look no further than UniFlex.

Reach out for polyurethane and rubber edges that are engineered and made just the way you want them to be.

Why is Polyurethane Used for Snow Plows?

The steel cutting edge has long been a mainstay for plows. Steel plow blades scrape and move ice and snow from surfaces like cobblestone and concrete. However, steel made plowing potentially damaging, ruining concrete and cobblestone surfaces.

As the demand for plow blades for residential areas grew, more manufacturers experimented with various materials.

Rubber plow blades became available as they proved to be friendly to residential areas. But, unfortunately, rubber was expensive to source. Also, it needs to be more flexible to bend on uneven pavement.

Homeowners desired something with the resilience and long life of a steel cutting edge and the flexibility of rubber edges. The polyurethane fills the gap between steel and rubber blades as an alternative material.

Polyurethane became the material of choice for plows, pushers, and blowers — thanks to the advantages of polyurethane for plow blade manufacturing.

Polyurethane Blades Have a Lower Friction Coefficient Than Steel Cutting Edges

When selecting snow plow-cutting blades, one of the qualities to consider is the friction coefficient. The friction coefficient determines the blade’s abrasive force on a plowing surface. The higher it is, the more friction a blade applies to a plowing surface. A high friction coefficient is desirable for most surfaces. However, a low friction coefficient material like polyurethane is superior for delicate surfaces.

A poly plow edge has a lower coefficient than its steel counterpart. Polyurethane edges can glide on a plowing surface and protect it from excessive abrasion and damage.

A Polyurethane Snow Plow Blade Has a Longer Life Than a Rubber Edge

Plowing can take a toll on even the most resilient or flexible materials. While rubber is flexible, it only takes a short time before the edges wear out. For long-lasting plowing blades, polyurethane is a better material than rubber.

Poly cutting edges are abrasion-resistant. Due to their polyurethane construction, they can withstand multiple plowings even at a fraction of the thickness of rubber edges. Polyurethane’s low friction coefficient also enables polyurethane edges to glide on any surface easily and avoid damage.

Polyurethane Cutting Edges Are Quiet

A poly cutting edge isn’t just protective of every surface. A poly edge is also close to noiseless. We can attribute the quietness of a poly cutting edge to its weight and friction coefficient.

Polyurethane cutting edges can glide on surfaces without causing much friction. As a result, you’ll hear no screeching noises as you plow snow or ice off your property’s surface.

Poly Snow Plow Blades Are Warp Resistant

Adding to the wear-and-tear resistance of polyurethane cutting edges is their warp resistance. Polyurethane is a stable material that doesn’t change when temperatures rise or drop. The polyurethane’s stability allows you to store your blade for a long time without the risk of its shape, width, and thickness changing whenever it gets hot or cold.

Unparalleled Shock Resistance

Due to its construction, a poly cutting edge is more resistant to shock than steel. Polyurethane boasts the elasticity and flexibility that enables your blade to bend on uneven pavement or residential surfaces.

A New Cutting Edge Costs Less Than Rubber

Rubber is flexible, safe, and easy to mount and customize. However, it’s not the most economical option despite being cheaper than steel. On the other hand, Urethane is more accessible to source and mold, making it a more affordable and equally effective alternative to rubber.

When you buy a polyurethane plow blade, you’ll get it at a lower price than a rubber blade. Many manufacturers are now offering affordable polyurethane edges. However, if you’re looking for the best deals for custom polyurethane blades, call us now for a free quote.


Polyurethane’s most salient advantage over steel and rubber is its moldability. As the most moldable material for plow blades, polyurethane is almost as easy to shape as plastic. As a result, the material lends itself better to customization.

Unfortunately, only some manufacturers have the logistics and manufacturing capabilities to customize plowing blades to your specs. This is where we come in. Reach out for custom plowing edges that fully reflect your exact specifications.

The Best Time to Purchase a Polyurethane Plow Edge is Now

When is the best time to buy a poly plowing edge for trucks, plows, and pushers? If you’re reading this, and it’s snowing, then the answer is clear — there’s no better time than now.

By ordering your edges during December, January, and February, you’ll be increasing the shelf life of your plow, blower, or truck. With that in mind, consider your new cutting-edge investment for your plow and residential surface.

When You Need Quality Custom Polyurethane Cutting Edges, Think UniFlex

Do you need custom polyurethane cutting edges explicitly molded to your desired specs? Look no further. Call us now for poly-cutting edges for trucks, blowers, and plows built to last and serve you well this winter.

When it comes to industrial plastics, there are two main types: thermoplastic polymers and thermoset polymers. Thermoplastics can be melted down and reused, while thermoset plastics cannot. Thermoset plastics are more durable than thermoplastics but are also more expensive. So, which material is used in the mining industry?

What is Thermoplastic?

Thermoplastic is a type of plastic that becomes soft and pliable when heated and hardens when cooled. Unlike thermosetting plastics, which cannot be softened once they have been set, thermoplastics can be melted and reformed multiple times.

Thermoplastics are used in a wide range of applications, from food packaging to medical devices. The most common thermoplastics include polypropylene, polyethylene, and polystyrene.

Thermoplastics are produced by polymerizing small molecules into long chains. These chains can be linear or branched, depending on the specific application. When heated, the chains break apart and flow freely, allowing the thermoplastic to be molded into different shapes.

Once cooled, the chains reform, and the thermoplastic hardens. This process can be repeated an unlimited number of times, making thermoplastics an extremely versatile material.

In the mining industry, thermoplastics are used for a variety of purposes, including:

  • Pipelining
  • Cable insulation
  • Hose reinforcement

What is Thermoset?

Thermoset is a type of plastic that becomes permanently hard when heated. Unlike thermoplastic, which can be melted and reformed multiple times, thermosets cannot be remolded or recycled. Common examples of thermoset materials include Bakelite, epoxy, and vulcanized rubber.

These materials are often used in applications where high heat resistance and durability are required, such as in electrical insulation or automotive brake pads.

Thermoset is able to mold into complex shapes just like a thermoplastic. However, it is usually open cast, low pressure injection molded, or compression molded rather than injection molded or extruded. Thermoset is also generally more expensive than thermoplastic. This is because the manufacturing process is more complex, and the raw materials are often more costly. This being said, thermoset polymers are often much more durable than thermoplastics and are extensively used in high wear environments wear longevity is essential.

In the mining industry, thermosetting plastics are used for:

  • Molding electrical components
  • Sheet material for liners
  • Aggregate screens
  • Roller coatings
  • Making gaskets and seals
  • Creating wear-resistant coatings

What’s the Difference?

Comparing thermoplastic and thermoset is a common occurrence because they are both used in a variety of applications. Here are the key differences between these two materials:

  • Thermoplastic can be melted and reformed, while thermosets cannot. This is because thermoset undergoes a chemical reaction when heated, which permanently changes the material. The curing process involves chemical bonding of the material properties to form permanent chemical bonds.
  • Thermoplastic is less durable than thermoset. Thermoplastics, such as food packaging, are often used in applications not subject to high temperatures or stress. Thermoset plastics are better suited for high-heat and high-stress applications, such as automotive brake pads. The material properties can withstand these and more because thermosetting materials undergo an extensive curing process.
  • Thermoplastic is generally less expensive than thermoset. This is because thermoplastic manufacturing is more straightforward, and thermoplastic materials are often cheaper. Thermoset plastics are more complex to produce and require more costly raw materials.
  • Thermoplastics are more manageable to mold into complex shapes than thermosets. Thermoplastics can be melted and reformed multiple times, making them more flexible during molding. Thermoplastic polymers are more flexible and versatile because processing thermoplastics involves guaranteeing thermal stability.
  • Thermoset plastics are more versatile and long lasting but often require chemical processing equipment to guarantee the chemical ratio integrity of thermoset plastic mixes.

What Type of Urethane Parts Are Used in the Mining Industry?

Urethane has many benefits that make it ideal for use in the mining industry. It is wear-resistant, impact-resistant, and can withstand high temperatures. As a result, urethane parts are often used in mining equipment, such as conveyor belt rollers, screen decking, and chute lining.

In addition, urethane can be molded into custom shapes and sizes, making it perfect for creating bespoke parts for specific applications. Thanks to its versatility and durability, urethane is an essential material for the mining industry. It can maintain good structural integrity and minimal chemical resistance.

The urethane parts that are used in the mining industry include:

Conveyor Belt Rollers

Conveyor belt rollers are used to move heavy loads along a conveyor belt. They are typically made from steel or urethane and are designed to withstand high temperatures and wear caused by friction.

Urethane is often used for conveyor belt rollers because it is impact-resistant and can withstand the high temperatures generated by friction. It is also less likely to damage the conveyor belt than steel rollers.

Screen Decking

Screen decking is used to separate materials by size. It is typically made from wood or urethane and comprises a series of screen panels attached to a frame.

Urethane screen decking is often used in the mining industry because it is wear-resistant and can withstand the high impact of falling rocks. It is also resistant to the corrosive effects of chemicals and moisture.

Chute Lining

Chute lining is used to protect surfaces from abrasion. It is typically made from rubber or urethane and is installed on the walls of chutes, conveyors, and other high-wear surfaces.

Urethane chute lining is often used in the mining industry because it is wear-resistant and can withstand the high impact of falling rocks. It is also resistant to the corrosive effects of chemicals and moisture.

Urethane parts are essential for the smooth running of the mining industry. Therefore, if you’re looking for mining equipment, check that the parts are made from urethane. Thanks to its durability and versatility, urethane is the perfect material for use in the mining industry.

Why We Use Thermoset Polymers in the Mining Industry

Thermoset polymers are a type of plastic widely used in the mining industry. These materials are prized for their excellent physical properties, high strength, durability, and resistance to heat and chemicals. In addition, thermoset polymers are often easier to recycle than other plastics.

As a result, they have become the material of choice for many mining applications. Some common products made from thermoset polymers include conveyor belts, pipes, and pump housings.

In each of these applications, thermoset polymers’ superior strength and resistance help ensure long service life. Thermoset polymers have become an essential part of the modern mining industry thanks to these benefits.

Chemical modification of the polyurethane coatings and mechanical properties offers a variety of unusual chances to solve challenges with performance qualities unmatched by any other materials.

Why Are Urethane Parts Essential to Material Handling?

The term “polyurethane,” frequently abbreviated as “PUR” or “PU,” refers to a group of polymers made up of organic units cross-linked by urethane.

Polyurethane may be made from various starting materials, unlike conventional polymers like polyethylene and polystyrene. This chemical diversity generates polyurethanes with a wide range of chemical structures, resulting in several uses. These include:

  • Rigid and flexible foams
  • Varnishes and coatings
  • Elastomers
  • Adhesives
  • Electrical potting compounds
  • Thermal stability
  • Fibers such as spandex and PUL

What Urethane Parts Are Used in Material Handling?

In the beginning, thermosetting polyurethane was intended to be used as a synthetic version of natural rubber during World War II. The adaptability of this novel polymer and its capacity to substitute scarce materials soon led to the development of numerous applications. After World War II, the polyurethane industry rose, and polyurethane PU became a used material in many industries.

Polyurethane applications are essential for material handling equipment to ensure a continuous supply chain and efficient manufacturing process.

The following are just a few examples of material handling equipment parts that polyurethane properties may provide to assist you in fulfilling your material handling equipment production demands:

  • Urethane Rollers
  • Urethane Bumpers
  • Urethane Gaskets, Washers, and Bushings
  • Urethane Gripper Pads
  • Urethane Linings for Various Components
  • Polyurethane Clamps
  • Diverters
  • Wheels
  • Conveyor Equipment Parts
  • Rigid Foams
  • Reusable Fabric
  • And many more

Here are some more advantages of using polyurethane properties in situations involving material handling:

  • Low tooling costs
  • Excellent capacity for bearing loads
  • Outstanding impact resistance
  • Excellent noise reduction
  • Outstanding efficiency
  • Resist water
  • Measurement stability
  • Free from harmful toxins
  • Long-term field wear
  • Decreased downtime
  • Lower costs of maintenance

Importance of Polyurethane Foams in Material Handling Equipment

The most popular type of polyurethane that is utilized extensively worldwide is polyurethane foam. It was commonly used for molding flexible foam cushions and seating, refrigerator walls, or thermal insulation. In just a short period, flexible polyurethane foam quickly replaced other upholstery such as car seats and furniture, shoe materials, and many more as the preferred option.

Due to their unique properties, polyurethanes can be modified to improve commercial and consumer goods and solve complex difficulties in material handling equipment.

Today, consumer and commercial products like bedding, furniture, automotive interiors, carpet underlay, and packaging are all cushioned with polyurethane properties, primarily in the form of polyurethane foam.

Flexible polyurethane foam can be created in various shapes and densities and is robust, comfortable, lightweight, and supportive. It is utilized in many items, including coatings, adhesives, mattresses, foam insulation, and shoe soles.

Importance of Polyurethane Fabric in Material Handling Equipment

In many aspects, polyurethane coating and properties improve the performance capabilities of fabric. There is a substantial layer of this polymer on many elastic fabrics. As a result, it can be used to create windproof and waterproof apparel while still enabling water vapor to permeate the fabric gently.

PU fabric is one great alternative to animal skins and other fabrics. It is more durable, flexible, and affordable. In addition, PU fabrics can be designed to look like natural animal skin.

Polyurethane fabric is a compound material cross-linked to the polyurethane that connects one or more layers of polymer resins with a woven or non-woven textile backing made of polyester, cotton, nylon, or ground leather. To make the Polyurethane coating appear more like animal skins, it is applied to just one side of the basic cloth.

Polyurethane fabrics break or wrinkle like genuine leather when stitched, collected, or tufted. Unlike vinyl, Polyurethane resins are constructed of a flexible polymer and don’t require an additional superplasticizer.

PU fabric doesn’t contain plasticizers, so there is no tearing or peeling, and it stays soft and comfortable for the entire time it is attached to the furniture. PU fabric and textiles may be decorated easily as well.

Since PU fabrics don’t produce dioxins, they are considered more environmentally friendly than vinyl. Although Polyurethane fabric can be more expensive to make than vinyl, it is less costly than natural leather.

Where Can Urethane Parts Be Purchased?

Urethane parts are now available online because of how prevalent and essential polyurethane materials are in material handling equipment. Urethane parts, however, are typically customized parts. They are created specifically for you based on your requirements and material handling machinery.

However, you may purchase urethane stock manufactured products like polyurethane sheets, rods, tubes, and bars online for standard material handling equipment parts.

Urethane and polyurethane have permeated many industries, including the automotive industry. For the last decade, polyurethane has moved from the aerospace niche to a mainstay in manufacturing vehicle parts and accessories. For its resilience and weight, polyurethane has found itself in many demanding applications in the automotive industry. This material has a growing number of use cases, as shown by the industry-wide adoption of polyurethane gaskets and urethane piston hydraulic seals.

We can also attribute urethane’s growing adoption to its superior resistance and tolerance to many chemicals. The moldability of polyurethane also enables manufacturers to mold custom parts to fit client specifications, like custom-fit polyurethane gaskets for use in high-stress environments. Indeed, polyurethane and urethane are taking industries by storm with each part created from them.

Learn more about how these elastomeric materials are changing the game with each car part manufactured.

What Urethane Parts Are Used in the Automotive Industry?

Urethane and polyurethane are often the go-to materials for this vehicle part — urethane seals. However, polyurethane seals are not the only parts that consist of polyurethane. These materials are also ubiquitous in polyurethane gaskets or o-rings. Of late, car manufacturers have also been using polyurethane as muffler mounts.

Let’s get into these automotive components in greater detail:

Urethane Seals and Polyurethane Seals

Polyurethane and urethane seals are the most common examples of vehicle parts consisting of elastomeric materials. Polyurethane seals, like the piston, are ubiquitous in a vehicle’s hydraulic components.

Urethane and polyurethane seals boast resilience, resisting high temperatures. Their tolerance to high temperatures and chemical resistance also makes them long-lasting alternatives to plastic and rubber seals.

Polyurethane seals also have excellent abrasion resistance. This makes polyurethane seals less susceptible to wear and tear, unlike rubber and plastic seals.

Polyurethane Gaskets or O-Rings

Automotive manufacturers also prize polyurethane and urethane for their chemical resistance. The tolerance of these materials to oil to ozone makes polyurethane or urethane an ideal choice for tube connections.

As a result of polyurethane’s chemical tolerance, manufacturers have used it to make polyurethane gaskets or o-rings. Polyurethane gaskets or o-rings provide excellent connections between tube surfaces, guaranteeing leak-proof connection under high heat and pressure.

Polyurethane gaskets also have excellent abrasion resistance, meaning they aren’t susceptible to wear. As a result, polyurethane gaskets and o-rings require only periodic maintenance or replacement.

Polyurethane Bushings

Rubber or OE suspension bushings have long been the ideal choice for every car manufacturer. Unfortunately, a vehicle’s suspension is the site of much wear and tear. For this reason, a vehicle owner can only expect rubber or OE bushings to last so long. For more longevity, a material like polyurethane may be a better alternative.

Polyurethane bushings share the hardness and durability of steel and high-density rubber. However, polyurethane bushings also have more “give” than metal materials. The resulting ability to absorb shock adds years to a vehicle’s suspension life. Also, the elasticity of polyurethane bushings reduces noise and vibration — two characteristics that many motorists desire.

Polyurethane Muffler Mounts

Manufactured muffler mounts used to consist of rigid materials like steel. However, the desire for noise reduction created a market for polyurethane muffler mounts.

Polyurethane muffler mounts reduce noise due to the polyurethane’s elasticity and shock absorption. These muffler mounts are also abrasion-resistant, requiring infrequent maintenance and repairs.

Why Are Urethane Parts Essential to the Automotive Industry?

Vehicle owners recognize the importance of a lighter vehicle. Reduced weight contributes to not only speed but also fuel and energy efficiency. For this reason, vehicle owners will scour the market for lighter parts that boast the same hardness and quality as metal or steel.

A manufacturer must, in turn, cater to the broad consumer demand for vehicle weight reduction. This is where parts like polyurethane seals and polyurethane gaskets come in.

Polyurethane Seals and Polyurethane Gaskets Feature the Perfect Balance of Qualities

Urethane and polyurethane gaskets and seals provide vehicle owners with lighter, abrasion-resistant, and elastic options. As a bonus, these parts compromise little in durability, hardness, and quality. They are ideal for any supplier or manufacturer catering to vehicle owners who desire alternatives to traditional materials like rubber.

Tight Tolerances and Resistance to Oil and Chemicals

Polyurethane’s elasticity makes it resilient to compressing forces in vehicles. The high-pressure benefits of urethane and polyurethane are apparent in components like suspension bushings and muffler mounts.

Besides their pressure resistance, polyurethane seals and gaskets protect against other chemicals. Polyurethane parts are resistant to oil and ozone and boast impeccable chemical resistance and hardness versatility.

Polyurethane Molds Easily

Often, metallic parts must be machined in advance. Worse yet, metallic stock items cannot be molded, so there will be limitations in the possible specifications of a part.

Urethane solves many production challenges by presenting manufacturers with a material that can be molded and machined easily. As a bonus, polyurethane parts can come in various levels of hardness and thicknesses, depending on what a client calls for.

Companies Can Manufacture to a Client’s Specifications

Part manufacturers can take advantage of polyurethane’s elasticity and mold components to client specifications. Manufacturers can mold polyurethane parts in varying three-dimensional geometries. Under tight tolerances, polyurethane components can also be molded for hardness and durability.

Custom Molded with Competitive Pricing

It costs more to cast metallic parts. As a result, manufacturers will charge more for car parts made of alloy or metallic material. By comparison, casting urethane and polyurethane parts costs less, making them more affordable than their metallic counterparts.

Custom Urethane Parts and How to Purchase

Polyurethane parts like seals, gaskets, o-rings, and bushings are typically not available off-the-peg. They are generally custom-made. Any polyurethane parts available online will usually come in standard colors and sizes. These parts may be of the right material but be unfit for a company’s needs. The only polyurethane and urethane products best purchased online would be stock items, such as polyurethane and urethane bars, sheets, rods, and tubes. These products are available from online suppliers. Of course, a company ordering these items must be able to cast or machine parts to make their product from stock urethane shapes. Otherwise, the company would have no alternative but to hire another company to manufacture urethane parts.

So, it is best to seek a company that not only has urethane and polyurethane but can cast parts with quality and precision. Not many companies offer this combination of services — but we at Uniflex, Inc. do.

With the demanding nature of the oil and gas industry, parts that are used in this sector have to be able to meet high standards. The parts must also withstand various conditions, including extreme temperatures, high pressures, and harsh chemicals. Urethane parts are often used in the oil and gas industry because they can meet these demanding requirements. Unlike rubber, plastics, and other materials, polyurethane offers hardness versatility, is durable, and is crack and wear-resistant. Urethane or polyurethane also offers high customization as it can be molded in different shapes and measures and can be used in applications typically found in areas that require oil and gas parts.

Parts made from polyurethane are also being manufactured for the automotive industry. From universal bushings that are used to replace worn stock bushings to specific replacements to rubber bushings of control arms, sway bars, transmission mounts, and other suspension parts, urethane bushes are being increasingly used for a variety of applications

What Are Considered Urethane Parts?

Due to the extreme durability of urethane material, stability in a downhole environment, and natural resistance to corrosion, pressure, impact, heat, and abrasion, it is the ideal tooling and parts-making material for the oil and gas industry. Many leading manufacturers, including Uniflex, have been taking advantage of this by exclusively making parts from polyurethane for the oil and gas sector. Because of its natural edge over rubber products and other plastics, urethane parts are slowly becoming the go-to material for many applications in this industry.

Here are some of the urethane parts that are used in the oil and gas industry:

  • Liners
  • Rollers
  • Outer Tube / Tubes
  • Bushings
  • Rings
  • Nozzles
  • Scrapers
  • Clamps
  • Seals
  • Gears
  • Pads

What Are Polyurethane Bushes?

A PU or polyurethane bushing or bushes acts as an inner sleeve of a control arm and other suspension parts. Bushes tend to be manufactured using rubber materials, but due to the advancement of polyurethane technology, many leading companies are now using this material for their bushing products. While hot rods, custom rods, and other old American vehicles are seen with rubber bushes, many of today’s vehicles come with polyurethane bushes because they are more flexible and durable and will not quickly wear, unlike their counterparts. In energy suspension, bushings made from urethane are the new norm. They can cast the outer diameter, fastener bolt diameter, inner sleeve, and wall thickness to achieve desired durometers (hardness).

Polyurethane Bushings

Polyurethane bushings — poly bushings or urethane bushings — are aftermarket suspension parts used to replace your car or truck’s rubber bushings. Because of their performance in automobiles, urethane bushings are also used in the oil and gas industry. They offer many advantages over their rubber counterparts, the most popular being improved handling and increased durability.

While polyurethane bushings will never be as soft as rubber, the suitable compound can get you pretty close. You can also custom-cast polyurethane bushings to cater to suspension components that require an inner diameter smaller than what is available on the market.

Some polyurethane bushings are also greaseable, meaning that you can inject grease into the bushing to keep it lubricated and operating smoothly. This is a great way to extend the life of your polyurethane suspension bushings and improve their performance.

Why Are They Essential to the Oil and Gas Industries?

The oil and gas industry often requires parts that can withstand extreme conditions, such as high temperatures and pressures. Polyurethane components can meet these challenges while still providing the necessary flexibility, strength, and durability. In addition, polyurethane is also resistant to many chemicals used in the oil and gas industry, making it the ideal material for various applications. The bushings generally works as an adapter for joining pipes, serves as a guide for installing other elements in the system, provides insulation, and more. Bushings also work to minimize energy usage, absorb vibration, and reduce noise.
