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.

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.

Affordability

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.

Injecting

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

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.

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.

Customizable

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!

Cost-Efficient

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.

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.
