Urethane sheets are versatile products that can be used in a variety of industrial applications. They are made from polyurethane, which is a synthetic polymer known for its durability and strength. It is far from a traditional material. Open cast urethane sheets can be used in the manufacturing, construction, and automotive industries, plus others that have lower tooling costs.

A Brief History of Urethane

Back in 1937, a German chemist named Friedrich Bayer first created the original blueprint for polyurethane, also known as PU or Perlon U. The year 1940 was marked as the year that saw the successful development of the first polyurethane elastomers. Their physical properties are comparable to those of rubber.

This new kind of material immediately became a cheaper option than normal rubber during World War II, which was an expensive commodity due to its scarcity. One polyurethane use was as a protective coat on the outside of airplanes used in the battle. Later on, researchers came to the realization that polyurethane could be merged with nylon to create a material that was not only lightweight, but also had elastic memory.

This elastic memory was accomplished by synthesizing the material into fine threads. The first commercial manufacture of polyurethane foam was in the United States in 1953. The foam was stiff and its primary use was insulation. This lasted only until 1956, when more flexible and less expensive foams entered the market. When moldable polyurethane was invented in the late 1950s, it was already being utilized as a binder.

The malleability of the material allowed for the development of new uses, such as the production of versatile pillows. The development of polyurethane has now progressed to the point where it can manufacture several useful types of materials, such as coating materials made of polyurethane, stretchy strands, and injection molded parts. Polyurethane components can be found in any number of things.

The Other Uses of Urethane Besides Plastics

Adhesives, coatings, and sealants made from liquid urethane are the most popular applications for this material. Urethane adhesives are used in the automotive and construction industries because they offer high bond strength, flexibility, and weather resistance. Coatings and sealants made from urethane protect surfaces from abrasion, chemicals, and corrosion.

Urethane is also used as an elastomer in tires, rollers, and other impact-absorbing applications. This material is well-suited for these uses because it has high abrasion resistance and can withstand compression without deforming. The product is also used to make gaskets and o-rings because of its excellent resistance to chemicals and temperature extremes.

The Basics of Urethane Sheets

When it comes to understanding industrial polyurethane, it is important to first understand the basics of standard cast urethane sheets. Urethane is a polymer that can be either rigid or flexible and is known for its high resistance to wear and tear. This makes it an ideal material for a wide variety of applications, in industrial settings and beyond. By understanding the basics of urethane sheeting, you will be able to make better-informed decisions about their use in your own projects.

What Puts the Poly Into Polyurethane?

Urethane is flexible and malleable, making it perfect for item sizing and manufacturing. It is a polymer, which is a long chain of organic units that are connected to each other through chemical compounds and can be derived from both natural and synthetic sources. It is the material’s molecular structure, which consists of long chains of alternating organic units, that gives it physical properties like hardness and resilience.

The real strength of urethane, however, lies in its versatility. It can be molded, cast, or extruded into a variety of shapes and sizes. And, because of its tear resistance, it’s often used in material handling applications.

When it comes to plastics, polyurethane sheets are in a category of their own. That’s because this versatile material can be either rigid or soft, depending on how it’s made. Polyurethane is created by combining a polyol and isocyanate, and the ratio of these two ingredients combined with curing agents determines the hardness of the final product.

Polyurethane sheets are often used in applications where physical strength is a must. This kind of material is flexible and does not permanently deform, so it works well for things that need to bend or give, like chute liners or pads. For material handling, where durability is key and a high degree of longevity is required, polyurethane reigns supreme.

Durometer Ratings, Thickness, and Common Measurements

Urethane sheeting comes in a wide variety of standard durometer ratings, thickness, and common measurements. When choosing a urethane sheet for your application, it is important to consider the stocked inventory dimension tolerances. This can help to ensure you are getting the right product for the job that will also best suit your needs.

Durometer Rating

Polyurethane formulations cover a very broad hardness range, from very soft to very hard. The hardness range of a urethane sheet is measured from 40 Shore A to 75 Shore D. On the low end of the scale, Shore 00 urethanes have a gummy feel and are used in applications where flexibility and lower impact shock absorption are key. On the high end of the scale, shore D urethanes are much harder and are used in applications where abrasion resistance and durability are key.


Cast urethane sheets are available in a wide variety of thicknesses, from 0.125″ to over 6″. These are measured in either English or metric units. When choosing the right durometer and thickness for your application, polyurethane flat sheet stock is available in thickness standard sizes. It is important to consider the weight of the object that will be resting on the urethane sheet as well as the desired level of thickness. This can help you determine whether you need a thin, flexible sheet, or a thick, rigid one.

Common Measurements of Urethane

Urethane sheets are conveniently available in standard stock size as well as custom sizes. Standard stock sizes are 48″ x 138″, 48″ x 120″, 48″ x 96″, and 48″ x 48″. These dimensions allow for easy handling and transportation of the sheets, which is ideal for many applications. Custom sizes are also available for those who need a specific size or shape for their project. This is to fit your specific application needs so you don’t have to worry about waste and can get the most out of your urethane sheet.

Urethane Sheets and Pigmentation

Standard cast urethane sheets can be made in a wide selection of custom colors to achieve the right look for your industrial application. In addition, urethane can be formulated to resist UV exposure, meaning that your custom colors will not fade over time. Urethane is also well-suited for applications requiring sharp edges. When it comes to industrial applications, urethane sheets offer a lot of advantages. With the ability to customize color and formulate for different purposes, urethane can be adapted to fit many needs.

Common Industrial Applications

As mentioned before, urethane sheets are often used in common industrial applications. These applications typically require a high degree of versatility, durability, and abrasion resistance. Whatever the application, urethane can be formulated to meet specific needs. It can withstand both high and low temperatures, making it ideal for a wide range of projects. Urethane also has excellent chemical resistance, which makes it a good choice for many industrial applications that involve harsh chemicals.

Liners & Covers

A good-quality urethane sheet will protect the surface to which it is applied. This is because urethane has high tear and impact resistance. It can resist abrasion, both from objects and from chemicals. Urethane sheets can be used to protect many different kinds of surfaces, including:


Urethane can be used to line and replace metal surfaces to protect them from wear and tear. It is much more durable than traditional plastics, and it will not tear or wear out as fast. When applied to metal, urethane can provide a long lasting buffer between media and the metal surface. This allows economical replacement and longevity for equipment.

Noise Abatement

It is often that a lot of noise is generated in industrial settings. From large factories to the mining industry, there always seems to be some form of metal on metal contact. This creates a lot of noise that is often distracting to employees. Urethane sheets can be used to provide a shock absorption pad between these metal surfaces which significantly reduces noise and wear.

Abrasive Material Handling

Urethane pads can be used to line surfaces that come into contact with abrasive media such as rocks, sand, coal, ore, and salt. We often see applications for sheet in the mining industry where large volumes of abrasive substances are processed through expensive equipment that needs protection. Another common application is with chute and hopper liners in the agriculture industry. Here, pu sheets line metal grain chutes and hoppers to protect against degradation.

Cast Urethane Products

Cast polyurethane products are created using a mixture of a prepolymer and a curing agent. Different prepolymers and different curatives can be combined in custom ratios that allow endless versatility. Because of this, polyurethanes can be manufactured in a vast hardness range from 10 Shore A to 75 Shore D. Additionally, a multitude of physical properties can be created through resin and curative combinations. This can include tailoring tear strength, chemical resistance, rebound, and compression set to specific jobs.

Depending on the project, cast urethanes can be used to create a plethora of products such as rollers, bumpers, wheels, bushings, etc. Though, one the most common uses is in stock shapes.

Some common stock cast urethane products include:


Polyurethane sheet is most often used as a liner to protect surfaces from wear. It is extensively used in the metal forming industry, mining industry, and automotive industry. It is very versatile and can be ordered in custom sizes and thicknesses. This allows cost savings and easy emplacement.


Rod made from polyurethane is an excellent replacement for traditional hard plastics like UHMW, HDPE, Nylon, and Delrin. Unlike these hard plastics, urethane rod is non-marring and will not deform when impacted. This is due to its elastics memory. Urethane rod can be manufactured in any length, diameter, and hardness.


Urethane tube can be made in standard or customized ODs and IDs. Lengths are generally 12″ to 48″. Common applications include springs, roller covers, protective sleeves, and liners. Cast urethane tubes differ from extruded tube as they use a thermoset urethane versus a thermoplastic urethane. Thermoset urethanes have much better physical properties.


Cast urethane bar stock is used as a machinable plastic for milling or turning urethane parts from stock. The advantage to polyurethane bar stock is that it outperforms traditional materials like UHMW. Furthermore, bar stock can be used in other applications such as bumper pads, squeegees, and belt scrapers.

custom sheet, bar, & rod

All cast urethane stock such as sheet, rods, tubes, and bars can be custom manufactured. Because of urethanes liquid starting state, it allows for endless versatility. Any durometer, size, shape, and color can be manufactured. Custom tubes, elbows, rods, blocks, and sheet are very common in the manufacture of polyurethane products. Orders can be filled fast and efficiently with little or no tooling costs.

Common Products that Use Urethane Sheets

Urethane is such a versatile material so there are many items that industry uses on a daily basis that are made with this polymer. Whether in the form of elastomer, foam, or castable liquid, urethane can be found in many places.

While most people don’t think about it, urethane is actually a vital material in many different industries and products. By understanding a little more about this material, you can begin to see just how important it is for your company.

These are a few examples of products that you have probably come into contact with something that contains urethane:

bench covers

Urethane sheet is often used as a bench top cover to prevent surface damage. Not only does it protect the table surface from marring, but it also protects the components on the table. Generally, assembly operations will use urethane pads to protect the components they are assembling on work tables.


One of the most common uses for polyurethane sheets is as liners. It is often seen in the agriculture industry as grain chute liners and hopper liners. You will also see urethane sheets in the mining industry being used as equipment liners and blast pads (among others).

metal forming pads

Metal forming pads require a great deal of tensile strength to withstand repeated, multi-ton impact. Polyurethane pads are excellent for this application and provide a long-lasting alternative to rubber.

mining industry Pads

Urethane sheeting is a staple in the mining industry. It is use to protect metal machinery from abrasive media such as gravel, sand, ore, and salts. In general its use is in aggregate handling where it provides a cost effective buffer for wear.


As you now know, urethane flat sheet stock offers a variety of benefits for industrial applications. By being abrasion resistant, plus by having oil resistance, wear resistance, chemical resistance, and insulation properties, it be used in so many applications that will improve the efficiency and productivity of your business.

Not only can you guarantee the quality of your finished product, but you can also save time and money in the long run. By considering all the urethane sheets applications, it’s easy to see why they’re becoming increasingly popular in the industrial sector.

Rollers are employed in a wide range of industries, including manufacturing, engineering, and construction. It’s difficult to imagine one trade sector that doesn’t use rollers in some capacity. They come in a variety of sizes and are often moving up and down or side to side at breakneck speeds.

Traditionally, rollers have been made of metal, although resin is a common alternative. More recently, polyurethane and rubber rollers have become popular materials for rollers in the industrial sector because they are inexpensive, durable, and easy to mold in production casting.

Polyurethane and Rubber Rollers

A lighter, more adaptable solution is often preferred for many industrial roller applications. In most sectors, polyurethane and rubber are increasingly being used because of their significantly lower expenses, how smooth on surfaces they are, and their greater structural versatility. These rollers also have a higher capacity to resist friction and abrasion than their metal predecessors.

Polyurethane rollers and rubber rollers have a lot in common, but they are not quite the same. It’s critical to understand the differences between these two types of rollers when selecting which of them is best for your industrial application.

What Is Polyurethane?

What Is Polyurethane

Polyurethane is a plastic material that can be used for a wide range of applications. It is an extremely versatile material that can be manipulated to be hard or soft, rigid or elastic. It may be poured into polyurethane molds, or brushed or sprayed on top of prepared surfaces. Polyurethane can reproduce exceptional detail in models.

Flexible urethanes are available in many different hardness levels. They can be soft like jelly or hard enough to replace metal components. Polyurethanes have low viscosity and self-degas, requiring no vacuum degassing.

However, on the downside, polyurethanes are susceptible to moisture buildup. Using a urethane mold in excess humidity on a hot summer day is not always a good idea. When compared to silicone rubber, urethane rubber is the worst because it sticks to almost everything.

Are Polyurethane and Rubber the Same Thing?

Are Polyurethane and Rubber the Same Thing

While polyurethane and rubber have some similarities, they differ in several ways, therefore they are not the same. Polyurethane is the material of choice for any project that requires superior abrasion, cut, and tear resistance. It can be made in higher hardness ratings to better bear weight while being chemical resistant. However, this material is more prone to negligible shrinkage.

Rubber’s flexibility, however, allows it to absorb vibrations and noise, making polyurethane appear inferior for vibration dampening to durable rubber. On the other hand, polyurethane is also a good energy absorber and can be produced with a very low durometer.

Is Polyurethane Better Than Rubber?

Is Polyurethane Better Than Rubber

Polyurethane outperforms rubber in applications that are either submerged or exposed to wet environments for a long period. This is owing to polyurethane’s higher resistance to moisture. Rubber would rot over time. Another added benefit is that polyurethane is also UV resistant.

Also, most industrial applications, especially those that include dynamic loads and high friction, expose rollers to a lot of abrasions. In both cases, polyurethane outperforms natural rubber. Consequently, if your roller will be exposed to dampness regularly, must carry a significant amount of weight, and must endure continuous friction, polyurethane is a superior choice.

Micro molding is a type of fabrication process that creates detailed structures in polymers on a micro scale using molds. The micro molds are made in a micro-tooling department where a cavity is carved into each mold that matches the shape of the part to be manufactured. The component or item can then be swiftly created by the micro-injection molding process. Here, thermoplastic or resin is injected into the cavity at a high speed.

When making micro parts, one factor to consider is “micro tolerance.” This refers to the minimal distance between the required measurements and design size that must be met in order for the micro component to be utilized. The concept assesses whether the margin of error is narrow enough to still work.

The stack-up tolerances must be within 1/100th of an inch in a micro molding process, though in certain situations the molded component must be within 1/1000th of an inch. Traditional injection molding can frequently produce small fragments that do not require such tight tolerances.

With traditional or conventional molding, it’s difficult to manufacture microscopic parts that measure less than a millimeter across. However, with micro-mold-enabling technology and specialized micro machining, we can create highly intricate and detailed plastic components at any size needed!

The Difference Between Micro Molding and Traditional Injection Molding

The procedure for micro-injection molding appears to be similar to conventional injection molding. A mold design and prototype are made, followed by the creation of a double-sided mold. However, there is a difference between the two injection molding processes.

Conventional injection molding is the process of forcing thermoplastics into a mold. Thermoplastic materials are melted in a furnace and then injected with a highly pressurized injection tool. When the molded parts have cooled and hardened, the item is removed.

Micro molding can be completed in the same way as conventional molding, but with a different micro-injection unit (built in the machine) necessary to accommodate the micro components.

Micro Molding Materials

Micro molding is often carried out with thermoplastics, thermosets, polymers, resins, and elastomers. Fortunately, there is a plethora of molding materials to select from when making micro molded parts. It is feasible to make a mold that is smaller than a dime by picking the appropriate material for the item you have in mind.


In many situations, handling and packaging seem to be an afterthought, but in reality, they’re often as essential as producing the part. Handling and packaging micro-sized devices is significantly more difficult than handling and packing macro-sized components, and the solutions are different. Molding and packing micro items so that they are useful to the end user is an important aspect of production.

Custom automation and packaging services may be provided in a variety of ways. They might range from reel-to-reel packaging to light subassemblies, high-speed automated packaging, lead frame die-forming and singulation, in-line automation, and a wide range of other packaging processes. These services go a long way to determine the success of a project.

How Extensively Is Micro Molding Used Across Industries?

Micro molding is used across several industries. It has become an important part of the manufacturing of numerous essential devices that make the modern world work.

In a lot of procedures in today’s medicine, such as minimally invasive surgery, precision is required. As a result, many medical equipment items must be tiny and highly sophisticated. Medical device manufacturing, therefore, relies heavily on micro molding processes.

There’s also a higher demand for high-precision, sophisticated work in the engineering industry. This is because modern electronic devices are getting much smaller and need tiny parts with extremely tight tolerances. Micro molding advantages may be applied to a variety of electronic component manufacturing such as micro-optics, hair-sized core pins, and so on.

These are just a few examples of industries where micro molding processes have became a critical factors.

Rubber bushings are a primary material that automotive manufacturers use in order to reduce the transmission of shock and vibration between parts. In other words, rubber bushing is the material used on shock absorbers. It minimizes noise and damage due to reduced vibration. Moreover, it increases comfort and safety when driving. In this post, we have compiled a list of some of the most interesting as well as pertinent facts about rubber bushings that you may not know.

The Invention of Rubber Bushings Happened in the 1930s

Walter P. Chrysler is credited with the idea of using rubber bushing in the automotive industry in 1932. He reportedly encouraged the adoption of vibration-isolating mounts made from rubber to reduce the noise and vibration of vehicles.

Since then, the usage of rubber bushings occurred in several vehicle components that usually produce a lot of noise and vibration. Today, shock-absorber mountings made from rubber are the industry standard among commercial vehicle and automotive manufacturers.

For the uninitiated, vibrations – when left unaddressed – cause a lot of damage to products. Also, they generate loud noises that are not only comfortable but also potentially dangerous to operators. Bushings made from rubber absorb all this noise and vibration.

Rubber, Polyurethane, and Other Materials Actually Make Up Rubber Bushings

Shock mounts or bushings are cushions that contain polyurethane, rubber, and metals – and not just rubber. In fact, these cushions are extremely effective in controlling the amount of movement in steering joints and car suspensions to absorb road bumps and diminish vibration and noise. The rubber used to make these mounts is vulcanized and bonded. Aluminum, stainless steel, and mild steel are the most common metals used in the process.

Rubber Bushings Are Suitable For All Types of Vehicles

Uniflex Inc.’s rubber bushes are perfect as mechanical joints on rail and road vehicle suspensions, captive cab mountings, gearbox mountings, engine mountings, and pivot arms. The rubber on shock absorbers plays a vital role in vehicle comfort and safety when driving, used for aligning and positioning steering and suspension parts.

These include torsion bars, control links, sway bars, and shock absorbers, of course. Rubber bushings must remain in robust condition to prevent rapid tire wear and issues with steering. In addition to shock absorber mountings, rubber bushings are perfect for gear sticks (in vehicles with manual transmissions) and double-wishbone suspension assemblies.

 Several Industries Use Rubber Bushings

While we have mostly discussed their usage in the automotive industry, many other industries and applications use rubber bushings as well, such as:

  • Aerospace
  • Drilling equipment
  • Highway equipment
  • Construction
  • Plumbing
  • Electrical
  • Specialized internal combustion engines
  • Bikes and skateboards
  • Consumer appliances and goods
  • Sealing applications (for tubes, pipes, and wires)
  • And more!

Rubber is a very adaptable material which is why it’s utilized in so many mechanical and commercial applications. From sealing components, tires, rubber plugs, and several other products, it can be used to make pretty much anything.

If you are a vendor of rubber goods, it is crucial that you only work with the most experienced and reliable rubber manufacturers – after all, your company’s reputation depends on it!

But choosing the right custom rubber manufacturing partner is not easy when the market is full of them. Don’t worry, that’s what we are here for. In this post, you’ll learn how to shortlist and pick the best candidate among the crowd.

Check Out Their References

When working with a custom rubber manufacturing partner, you want someone who has a reputation for providing good customer experiences. A company that focuses on their customers’ satisfaction would be happy to share their references with you.

These references might be individuals or companies that contracted the manufacturer for rubber components for OEMs or major brands. Reach out to them and talk to them about their experience with the manufacturer.

But keep in mind that most major companies require their suppliers to sign a Non-Disclosure Agreement. Still, if you can confirm that the manufacturer is supplying to OEMs, you know they are the real deal in terms of reliability and quality.

Evaluate Their Competency

Despite the macro-economic challenges facing the rubber industry following the pandemic, if a business is still growing, it reflects on their intrinsic competence and resourcefulness. So, check to what extent the rubber manufacturing company has been active and whether or not it has been going through continuous improvements since its inception.

Ideally speaking, the company should be at least 5 years old with an established market reputation. Experienced suppliers would have worked with a number of businesses in different industries, which gives the much-needed versatility to handle your unique requirements.

Consider Their Business Ethics and Values

The world is changing and so is the way we do business. Experience and quality of products matter but you should also know the core values and ethics of a company’s business operations. Do they have complaints against them online about shoddy business practices? Are they providing their workers a safe environment and following all the local regulations and best business practices?

Working with a dedicated and responsible manufacturer means you’re supporting a business that truly cares about wellbeing of people and will treat you with the same respect and consideration.

Superior Quality Products

The most important deciding factor is obviously the quality of rubber products. Can the rubber manufacturing partner guarantee exceptional quality? To determine this, check their professional references so you can see their qualifying credentials. We also recommend requesting a few samples of their work if possible.

It may be tempting to go with the cheapest manufacturer, but this can prove to be a costly mistake. Remember, you get what you pay for. A manufacturer quoting “too good to be true” prices means they will be cutting corners somewhere; it could be in the quality of the materials or somewhere else.

Injection Rubber Molding

This process involves collecting raw rubber material (stock), which we then put it into a hopper that’s suspended over a conveyance belt. Then, the release of the stock follows together with processing via a channel whose equipment consists of a turning screw.

As the stock reaches the end of this channel, the complete melting of it happens due to a combination of the friction caused by the screw’s motion and the heating components inside the channel. A mold cavity lies at the end of the channel into which the injection of the liquid happens. Once the rubber cools and hardens inside the mold, its removal follows.

Compression Rubber Molding

This process involves pre-weighing, pre-measuring, and pre-heating the stock before inserting it into a pre-shaped mold cavity. Then, the closure of the mold follows in order to compress and squeeze the stock until it expands to take on the mold’s shape. Once the product cools and hardens, its removal is possible. The compression process is usually followed up by another process to remove the excess flash or material.

This is the cheapest way to manufacture large, intricate products.

Liquid Injection Rubber Molding

This process is pretty similar to the regular injection molding described above with one main difference: liquid stock is used as the raw material. The machinery used in the process also contains a metered pump as its equipment. It helps regulate and control the flow of the stock.

This pump releases the liquid, which is then mixed with some additives. Then we use a nozzle to inject the mixed stick into a shaped mold. The mold is closed tightly with clamps and an appropriate amount of pressure. Plus, the application of the heat follows in order to create the desired product.

With liquid injection rubber molding process, the creation of products is quicker since we don’t need to liquefy the stock first. Plus, the molded products require little to no finishing once complete.

Insert Rubber Molding

In this process, we form or mold rubber components around non-rubber inserts. Some of the most common insert products include surgical tubes and knife blades.

Boaters today can enjoy the comfort and luxury of home inside nearly any sea vessel, thanks in part to foam made from polyurethane (Flexible Polyurethane Foam or FPF). It makes carpet pads and seat cushions firm but super soft and also keeps bedding materials comfortable and supportive. It can also be molded to fit into those tiny, hard-to-furnish corners found on boats.

The Best Combination of Factors

Uniflex Inc. works closely with boat manufacturers to find the best combination of factors to meet the needs of the high seas. Such factors involve: 

  • Foam density
  • Resiliency
  • Softness
  • Affordability 

Based on your needs, the polyurethane foam can also be made temperature-sensitive and visco-elastic to continuously fit to a person’s desired shape. Doing so helps to minimize pressure points, relieve stress, and provide immense support. But foams aren’t the only polyurethane application for the marine industry. Another huge staple of the marine industry is solid cast urethane elastomers.

Marine industry cast urethane parts resist water absorption, obviously, but they have all the good qualities of metal and rubber. Marine industry urethane parts are as durable and tough as metal but also as flexible as rubber.


In addition to these properties, the diverse range of hardness (Durometers) allows our engineers to design parts that are ideal for boat construction. Components in which urethane has now replaced traditional materials including: 

  • Urethane:
    – Rollers

    – Wheels
    – Impellers
    – Sprockets
    – Wear plates
    – Sleeve bearings

Custom molded polyurethane parts are inarguably some of the most versatile solutions on the planet today. We can essentially mold polyurethane into anything, from car seats and furniture to skateboard wheels and urethane coated rollers.  

In other words, polyurethane is pretty much the ideal material for almost all parts needed for manufacturing and industrial purposes. It doesn’t wear nearly as fast as other materials and is resistant to:

  • Extreme temperatures
  • Abrasion
  • Chemicals
  • Moisture
  • And a multitude of other environmental factors. 

The key is to procure your custom urethane parts from a trusted and reliable manufacturer so that you can get the product with the exact specifications and quality that you want.

Let’s get into more detail about this wonder of modern science and its many applications.

What Exactly Is Custom Molded Polyurethane?

Businesses all around the world use polyurethane parts in their operations. They use custom molded polyurethanes in one form or another every day – such urethane conveyor rollers in assembly plants, FDA compliant urethane seals in food and beverage operations, and urethane storage pads for metal coils . Since polyurethane starts as a liquid compound, it can be molded into almost any shape, making it the material of choice for a wide range of end-user applications like: 

  • Rollers
  • Bushings
  • Protective covers
  • Bumpers
  • Seals
  • Body blocks
  • Storage pads
  • Scraper blades
  • Wheels
  • Chute liners

Because polyurethanes have such excellent properties, they offer versatile solutions to the challenges of eco-design and longevity. The modern polyurethane industry is continuously looking for ways to reduce waste and boost product performance. This has led to innovative techniques to increase energy efficiency of manufacturing processes and improve product quality. The end result – custom molded polyurethane – is now better than ever and costs far less.

History of Custom Molded Polyurethane

When Professor Dr. Otto Bayer created polyurethane back in 1937, it was mainly used as a replacement for rubber during World War II. At the time, rubber was hard to obtain and super expensive, so polyurethane proved to be a surprisingly durable and resilient replacement material. Its was mostly used for coating during the war, specifically for resistant clothing and airplane finishing.

By the 1950s, many products contained custom molded polyurethane including:

  • Rigid foams
  • Elastomers
  • Adhesives
  • Flexible cushioning foams

Have you ever considered what makes your car’s seat padding so nice and cushion-y? That credit goes to polyurethane, and we have been using it to pad car seats and furniture since the late 1950s.

As time went on, many further developments happened and today, polyurethane makes up a big part of our everyday lives. With that said, while most consumers don’t even know about this incredible material, the truth is, the modern life will be hard to imagine without custom molded polyurethane.

Today, it’s usage occurs in creation of a variety of things in the industrial sector such as rollers, bumpers, pads, bushings, protective covers, and a host of others.  As one of the most competitive and capital-intensive industries, the marine industry has also adopted urethane parts for a diverse range of applications.

Marine Industry: Urethane Parts Used in Underwater Applications

Urethane ticks all the right boxes when it comes to a highly versatile and resilient polymer material in the modern world. It can be cast and molded into countless shapes, and it doesn’t rot or wear out like other materials (think rubber). 

In addition, urethane is resistant to wet environments, making it perfect for various applications for the maritime/marine industry. The fact that urethane has remarkable impact strength and flexibility, makes an even more compelling case to use this material. 

Urethane epoxy resins are frequently utilized in sealing boat hulls from water since the material is completely resistant to corrosion and weather elements. But urethane’s usefulness goes beyond this because precise customization of marine industry urethane parts and equipment to your needs is possible.

It has high load-bearing capabilities, allowing it to carry heavy equipment on the ocean. And as if that wasn’t enough, urethane doesn’t absorb water and prevents fungal and algal growth.

The most common marine industry urethane parts used today include:

  • Polyurethane rollers (for boat trailers) 
  • Polyurethane drawers
  • Urethane:
    – flexible grab handles

    – blocks and bearings
    ice chests
  • Polyurethane shocks
  • Polyurethane impellers 
  • And many more 

What Are the Benefits of Using Marine Industry Urethane Parts?

Some of the advantages of using urethane for your marine operations include:

  • It doesn’t absorb water
  • Moreover, it is resistant to salt water
  • It has great shock- and vibration-absorbing properties 
  • Also, it is UV stabilized (when the color red or black is used)
  • Furthermore, it doesn’t allow the growth of fungus, mildew, mold, or algae
  • It doesn’t oxidize even after prolonged exposure to water and extreme environments
  • It is highly resistant to abrasion
  • Placement in tropical or humid locations is possible
  • It has high load-bearing properties
  • You can glue or drill it into fiberglass
  • And, you can formulate it for seals, door stops, bumpers, etc.

Simply put, marine product designers and engineers prefer urethane because it provides longer service compared to rubber and plastics. On top of this, it has lower noise-abatement properties when compared to metals.
