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.

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.

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.

What is Urethane?

Urethane or polyurethane, is sometimes referred to as a hybrid product due to its versatility; it offers the durability and toughness of metal while having the elasticity of rubber. However, it is not made of either of these things; instead, urethane is made from natural compounds known as isocyanate and polyol, which are bonded by carbamate to make them strong. These are just the starting blocks – polyurethane can be made to be more complex using a wide range of materials.

As it can have so many chemical variations, polyurethane can be created and used for a nearly unlimited number of applications. It can be made into both flexible and rigid foams, adhesives, bumpers, coatings, varnishes, and more, as well as fibers like spandex. With that said, foam is the most common application, accounting for 67% of the polyurethane produced in 2016.

Urethane has a wide range of hardness levels, from soft and flexible to as solid as a rock. The hardness is measured by durometers. The lower the number, the softer the material; low durometer readings correspond to low compression set characteristics.

Urethane’s versatility allows users to replace plastic, rubber, and even metal in their daily applications. It has superior physical properties along with excellent abrasion resistance, meaning polyurethane products can last longer and help to reduce production and maintenance costs.

Many companies rely on polyurethane to maintain their budget, cut production time, and reduce their operations downtime, while paying a fraction of the cost of other materials. This resilient and tough material is also a great choice if you’re looking to outperform rubber or steel because it can be molded into any shape you need while retaining the characteristics of those other two materials.

Additionally, polyurethanes can lessen noise and control shock and vibration in most environments. All of these great benefits are rolled into one material. You can create custom molded parts from polyurethane to work in any capacity you need. Urethane is the best of both worlds – versatility that meets the highest standards in the industry.

What Are Urethane Rods?

Urethane rods are made from thermoset polymer, a material that can retain its flexibility, shape, and resilience. Once formed, the rods can retain these physical properties under tension, compression, or stress, but can be molded into any shape, hardness, or size, making them highly versatile. Urethane rods also possess better aging, tear, and abrasion resistance compared to other materials.

The material also offers a higher load capacity, without displaying any deformation issues. Furthermore, polyurethane rods will provide better impact resistance, elastic memory, and wear properties compared to other kinds of plastics. Polyurethane rods come in a wide range of options, such as:

• Standard round rod stock sizes
• Custom round rod stock sizes
• A range between 40A–65D durometers
• Various colors, sizes, and lengths

How Are They Used?

Urethane rods are often used as an alternative to nylon or plastic components to provide an upgraded function. They also go beyond the standard color of black. Depending on your needs, you can get a urethane rod that can offer better resistance to oil, abrasion, weather, and wear. These can be made to be four times stronger than nylon, allowing them to last longer through various applications.

What Is a Urethane Sheet?

A urethane sheet is a type of elastomeric or rubber-like material that exhibits high elasticity, strong abrasion resistance, and excellent tear resistance. It can provide a higher load-bearing capacity. It is also characterized by its low compression set, meaning urethane will retain its shape even after being subjected to repeated stress or strain. A urethane sheet is often used in applications where durability and flexibility are key so the custom molded parts can withstand both high impact and extreme temperatures.

How Are They Different from Polyurethane Sheets?

While the words urethane and polyurethane sheets are often used interchangeably, there is no difference between the physical properties. The only difference is in the name. Polyurethane sheets and urethane sheets are the same thing. They are made from thermosetting materials so they can’t be reshaped or heated up. However, a urethane or polyurethane sheet can be machined if needed. Both urethane and polyurethane products are one in the same and have a high resistance to abrasion and tearing.

Why Is It Easier to Buy Urethane Sheets Online?

No matter what kind of project or use you need it for, you can’t go wrong with polyurethane sheeting. It works for all sorts of applications and comes in a wide array of colors and durometers, making it one of the most versatile materials available. Manufactured from thermoset urethane material, polyurethane flat sheet stock cannot be reheated or reformed, but can be machined.

Polyurethane sheets have a superior physical properties and quality so they can outperform products that are manufactured from rubber and many other traditional materials. Furthermore, polyurethane sheets can be used in a vast array of industries, which is why they are consistently in high demand. They are also the preferred choice because of their relatively low production cost and short manufacturing lead times.

In this blog post, we share everything there is to know about polyurethane sheets. We also provide in-depth knowledge about why this ultra tough material is the ultimate option for all your industrial needs.

Why Urethane Sheets?

Urethane flat sheet stock has the ability to provide reliable performance and endure all kinds factors in different applications. It is one of the most preferred materials in a variety of industries. This is especially true for standard-cast polyurethane sheets, which can be used as media blast material, as well as chute liners, protective covers, and forming pads.

The Importance of Urethane Sheets in Manufacturing

Urethane characteristics are extremely versatile so this elastomer is used throughout the world in all kinds of industries for a variety of applications. There are many advantages polyurethane has over other materials; it is tougher, stronger, more adaptable, and more durable. It can provide better value compared to parts made from other materials which will often break, crack, swell, tear, and deteriorate.

Urethane as a Material

Urethane boasts a higher load-bearing capacity and can withstand a tremendous temperature range without becoming brittle or cracking. As a result, this impressive elastomer has resistance to many environmental hazards, including:

• Abrasion
• Compression
• Impact
• Oxygen and ozone attacks
• Chemicals

Polyurethane sheets have many chemical compounds and can boast up to ten times higher abrasion resistance compared to other elastomers. It can even provide long-term water stability. As an abrasion-resistant material, it has excellent tear and tensile strength, plus a higher load-bearing capacity. Polyurethane sheeting is the ideal choice for a wide array of tough applications.

Depending on the usage, polyurethane flat sheet stock can be a better choice than metals because it’s a very resistant to wear. Its higher load-bearing capacity can be measured in tension, compression, and shear, where it can be made into polyurethane components that are thinner, lighter, and more durable. Because of these unique properties, the machinability of hard urethane is similar to both metals and plastics.

A Brief History of Urethane

Polyurethanes were first created in 1937 when Friedrich Bayer, a German chemist, developed Perlon U. It is known as the earliest prototype of the polyurethane polymer. It wasn’t until three years later in 1940 that the first successfully developed polyurethane elastomers appeared. Polyurethane elastomers had similar physical properties to rubber so they were often used as a replacement in many applications during World War II.

Later on, scientists discovered that synthesizing polyurethane and combining it with nylon resulted in a stretchable and lightweight material. In 1953, polyurethane foam was first commercially produced in the U.S. It was rigid and could be ideally used as insulation – although this changed when a cheaper and more flexible variant was introduced in 1956.

During the late 1950s, polyurethanes began to be used as adhesives and moldable urethanes were developed. This moldable material with elastic memory allowed for even more applications, which included flexible cushions. Today, development in polyurethane has been further refined to create more materials, including:

• Polyurethane coating
• Thermoplastics
• Spandex fibers

Urethane Specifications

There are many reasons why polyurethane sheets are the go-to option in various industries. Urethane characteristics are almost boundless; below are the specifications for this highly versatile material.

Durometer Specifications

When considering the hardness and range of production behind urethane, it is one of the most versatile materials available. This material has a durometer measurement that can range from as hard as a bowling ball to as soft as a marshmallow. Many polyurethane flat sheet stocks can be graded across three different durometer standard stock sizes and can offer a full range of hardness, which can be seen below:

• Shore OO: This scale is used to measure very soft materials.
• Shore A: This scale is used to measure rubber as well as many other elastomers; it is the most common scale.
• Shore D: This scale is used to measure harder materials such as rigid plastics.

With this scale in mind, you should also remember that a durometer standard stock size is only a general indicator of a material’s physical properties, but it won’t be able to accurately assess just how versatile urethane is. If you’re not looking for a certain hardness, you can look into other tools for measuring other properties, such as:

• Shock-absorption
• Rebound
• Temperature resistance
• Flex strength
• Water / chemical resistance
• Stretchability
• Superior impact resistance

The durometer standard stock size is one of the most readily available metrics, but not the only one to consider when looking into polyurethane products.

Formulations and Their Effects

Polyurethanes are the result of a chemical reaction between an isocyanate and a polyol, creating a pre-polymer. This is then cross-linked to a curative, forming the polyurethane – this may seem like a simple and straightforward chemical formula, but there is a lot of room for variability and more complex results.

For example, thermoset polyurethanes are typically made up of Toluene Diisocyanate (TDI) and Methylendiphenyl Diisocyanate (MDI). These are chemicals used to make many household products and offer good properties at both low and high temperatures.

Each of these unique combinations will create different chemical bonds and can result in different physical properties in the material. Moreover, there are many chemicals that can be added as curatives for polyurethanes, which opens up the possibility of creating something completely new.

With this many factors involved, it’s not hard to come up with an endless variety of combinations and formulations just by making small adjustments to the base formula. This is why product teams and engineers need to evaluate all of their urethane products and avoid choosing results according to just one or two criteria. Throughout the product development process, it’s imperative for creators to take the urethane formulation into account.

Chemical Resistance and Interaction with Oils, Hydrocarbons, and Solvents

Urethane is inherently oil resistant and solvent resistant, meaning anything made from polyurethane components will do well when used in applications that expose it to oil and fuel. One thing that can considerably influence urethane chemical resistance is the chemicals used to make it. As such, it is highly critical to understand these essential pieces of information about the environment and stresses that the product will be put under.

Knowing this ahead of time will ensure that users will have the right kind of formulation in the urethane they’re interested in and that it can answer their needs. Apart from chemicals, urethane’s resistance to various solvents can be affected by the duration of contact with the substance, different temperatures, and even the concentration of the substance.

When it comes to water, oil, and grease, urethane’s material properties can stay stable, with only a small amount of swelling in some cases. Furthermore, urethane can hold up its form against a wide range of chemicals, and is also solvent resistant, provided that the chemicals’ pH levels aren’t too basic or too acidic. Urethane components are most resistant to neutral pH levels.

Urethane in Manufacturing

You may already know how often urethane is used in manufacturing, but knowing further details can help you determine why it is the preferred choice. Below are just a few of the most common industries where you will see polyurethane flat sheet stocks in action.

Common Applications

Polyurethane sheets are an elastomeric material that come in varying colors and hardness ranges, with a standard size of up to around 6 inches thick. Variations in both the physical and mechanical properties can range from a rigid, high-density sheet – this will have a durometer measure of Shore D – to something that’s much softer. Because of their hardness and abrasion-resistant properties, polyurethane sheets will generally perform better against metal, plastic, and rubber components.

Moreover, polyurethane is known to handle fatigue well and has an excellent load-bearing capacity, is cut resistance, and has resistance to other environmental factors. The elastomeric composition of polyurethane flat sheet stock can be both flexible and rigid so it is commonly used in construction, where its resistance to the environment is heavily advantageous for wear resistance. Polyurethane sheets can be also combined with cast-in reinforcement materials, such as glass, graphite, and fiberglass for more applications.

Common Elastomer Applications

#1. Material Handling

Provides longevity in applications such as chute liners, hopper liners, and concrete forms.

#2. Metal Forming

Provides elastic strength and protection against compressive forces that are incurred during metal stamping and metal processing.

#3. Grain Handling

Used extensively in the agriculture industry as liners for grain bins, hoppers, elevator buckets, valves, and chutes.

#4. Aggregate

Provides excellent wear resistance against abrasive media such as sand, rocks, concrete, and ore. Generally used as a liner to protect metal components.

Other Non-Elastomer Applications

Industrial Settings

Rigid, low-density polyurethane has a wide range of uses, with the biggest one being in applications for thermal insulation. When a building is constructed, it is imperative to insulate the walls with low-density rigid polyurethane flat sheet stock to significantly reduce cooling and heating bills. This is possible because polyurethane sheets can keep the heat in during winter and out during the summer.

As a result, you will be able to cut carbon emissions from your home or commercial property while helping to limit the negative impact that expending energy will have on the planet. Furthermore, polyurethane flat sheet stock has a life span of more than five decades and won’t need any maintenance. As such, it is the ideal choice of material for those looking to build a new construction.

Residential Settings

Polyurethane sheets and products can be molded into foam that can be used in a wide variety of furniture. This kind of foam comes in different qualities, durability levels, firmnesses, and densities. Those with higher quality and density will often result in a higher price (usually sold per sheet by the quarter-inch).

Softer and more temporary foams are used more often for short-term pieces like those in baby mattresses. On the other hand, luxurious, top-of-the-line polyurethane sheets will usually be reserved for things like bay window cushions. Finally, the fabric found in standard car seats will often be made from polyurethane, because it is both durable and comfortable.

Advantages Over Other Materials

There are plenty of reasons why many people prefer polyurethane flat sheet stock over other materials. Here are just a few:

Very broad hardness range

Polyurethane products have a very broad hardness range based on the pre-polymers’ chemical and molecular structure. As a result, their hardnesses can range from anywhere between 20 Shore A to 85 Shore D.

Flexibility

Polyurethane sheeting can be very flexible and is the preferred choice for various applications. It has good recovery and elongation properties.

High load-bearing capacity

Because polyurethane can carry heavy loads in terms of both compression and tension, it can be used in all kinds of applications. While it may change in shape under huge loads, its elastic memory means it will always go back to its original shape once the load is removed.

Superior impact resistance

Polyurethane is an ideal solution in challenging projects because of its high tensile properties and high tear resistance.

Oil, grease, and water resistance

Polyurethane sheet can potentially last for many years when applied in subsea environments. Its properties also allow it to remain stable in oil, grease, and water with minimal swelling.

Wide resiliency range

Because it can be created to become hard, urethane products have high resiliency and may be a good electric insulation choice. If you’re looking for shock absorption, look for low rebound compounds with a resilience range between 10% to 40%. If you need quick recovery with your polyurethane flat sheet stock, look for high-frequency vibrations in compounds with a resilience range between 40% to 65%.

Mold, fungus, and mildew resilience

Many polymer-based polyurethanes don’t allow for growth of any kind, whether it’s fungal, mold, or mildew. This material is highly suitable for tropical environments. Furthermore, special additives can be added to improve resilience in polyurethane flat sheet stock and other related materials.

Strong bonding properties

These sheets can bond to many kinds of materials during the manufacturing process, including metals, wood, and other plastics. Polyurethane is the ideal partner for rollers, wheels, and inserts.

Great performance in harsh environments

Urethane products are highly resistant to extreme temperatures, including all kinds of tough environmental conditions. This is due to the chemicals used in their creation, which rarely cause degradation in the material.

Short production times

When compared to traditional thermoplastic materials, the urethane flat sheet stock option has a shorter lead time. It also has lower production costs compared to traditional materials when custom sheet sizes, colors, and durometers are required.

Cost Differences

When compared to other parts made from plastic, urethane parts will have a somewhat similar cost. However, making the casts for urethane products will cost less, since most casts will be made out of affordable metal. Other sheet extrusion methods may provide cost savings in mass but they require larger scale production volumes and do not provide the same physical properties as hot cast urethanes. In the long run, cast urethane sheet is more cost-effective than extruded urethane sheet because it will provide better physical properties and custom, low waste production.

Metal, another polyurethane competitor, is more expensive to manufacture. Casting metal cannot be done without the use of heavy-duty machines and welding processes. These extra steps aren’t needed for casting urethanes, which is much more straightforward.

When compared to rubber, polyurethane has higher material costs, but is less expensive to manufacture. At the point of purchase, polyurethane will cost slightly more than both synthetic and natural rubber. Be that as it may, polyurethane usually lasts longer than rubber materials.

Conclusion

Polyurethane flat sheet stock is among some of the most powerful, flexible, and versatile material available on the market today. It has useful chemical properties, it can be as soft or as hard as needed, it is abrasion resistant, oil resistant, and solvent resistant, and it can be used in many different projects, both industrial and residential. Additionally, the base formulation for the urethane flat sheet stock can be easily changed to serve any purpose the manufacturer needs and as a result, it has a near-infinite variety of combinations.

Over the last 50 years, nearly everything about food has undergone a significant change – how we cook it, buy it, eat it, raise it, grow it, and package it. The modern food and beverage industry is much more focused on sanitation, hygiene and safety in their production, packaging, and distribution practices to eliminate the risk of contamination.

In this post, we will take a look at some of the vital facts you need to know about food-grade urethane pertaining to the food processing industry today.

Transition From Cheap Plastic To Food Grade Urethane

As seals and gaskets are two of the most significant components in almost all food processing systems and equipment, they also have undergone major modifications. Instead of using the seals and gaskets made from standard plastic materials – which was the norm up until a couple of decades ago – the food processing manufacturers are now making use of food-grade urethane.

This change occurred after the industry leaders realized that most of the sanitary issues and food contamination are caused by gasket/sealing units made from subpar quality materials. While there are many options when it comes to gasket materials, such as Viton, silicone, and EPDM, food-grade urethane or polyurethane is the only FDA-approved material due to several reasons:

• It has high abrasion and impact resistance and will not crack, tear, or break easily.
• It has an extremely high load-bearing capacity.
• It has exceptional tear-resistance and high-tensile properties.
• It is capable of demonstrating high mechanical strength even at exceedingly low temperatures.
• It is resistant to harsh environmental factors involving acids, oils, solvents, and heat.
• It possesses a wide molecular structural variability.
• It lasts much longer than other gasket/sealing materials such as plastic, silicone, rubber, fiberglass, felt, and neoprene.
• It prevents the growth of mold, mildew, and fungi even when it is in constant contact with edible or liquid items.
• It is resistant to aromatic hydrocarbons, and vegetable and mineral oils.
• It offers superior performance at temperatures ranging from -30°F to 220°F

Choose FDA-Compliant, Food-Grade Urethane For Your Food Processing Applications

Under section #177.21000, subpart F, food grade urethane is acceptable for repeated contact with edible items. If you’re looking for non-allergenic, non-marking, and non-toxic material for your food-related operations, FDA-approved polyurethane is the perfect choice.

In addition to gaskets and seals, applications include:

• Transfer systems and hoppers
• Feet and bumpers
• Wheels and bumpers
• Inspection tables
• Chutes and chute liners
• Conveyor systems
• Sprockets
• Belt scrapers
• Custom molded parts

Contact Us For Quality, FDA-Approved, Food Grade Urethane & Polymers

Rubber seals prevent the unwanted leakage of liquids and gases in various components. For example, they are used on pumps to keep them from leaking out too much oil or developing air bubbles that could cause problems with their operation. Rubber seals may also be utilized on valves, vacuum seals, pipe joinery, and much more.

However, not all seals are built equal. The design of a rubber seal has numerous components to ensure that it performs well in any environment. An O-ring, for instance, is a common industrial rubber seal that relies on mechanical compressive deformation to function as a barrier between mating surfaces, restricting liquid or gas flow in specific regions.

As a result, several elements must be considered in the way an O-ring shape is designed to ensure that the compressive force is sustained and that a good seal is achieved. Here are a few more facts about these rubber components you should be aware of:

They Are Your Best Bet Against Damages

Rubber seals have many different characteristics that make them useful in a variety of situations. Flexibility, elasticity, strength, and friction are just a few of the properties that come to mind when thinking about rubber. They also help to prevent vibration and are airtight.

Good quality rubber seals are the key to avoiding water damage. The long-lasting benefits and ability to prevent leaks make rubber seals popular in an extensive range of industries. This includes the construction industry, where they can be used for protecting against moisture exposure that may cause corrosion in metal parts below ground level. These rubber products are also utilized in preventing weathering damages.

They Are Useful Across Many Industries

The durability of rubber makes it a favorable and stable material for many applications across different industries. This versatility means that even with changes occurring in the environment such as frequent temperature fluctuations or exposure to chemicals, you can be sure your product or machine parts will last longer than expected!

Rubber seals are an excellent option for any company in sectors that utilize a lot of machinery to manufacture products. They are ideal for firms involved in mining, manufacturing, oil and gas extraction, and so on.

They Are Different From Rubber Gaskets

Gaskets are helpful in any application where you need to seal off spaces. You can find them in home appliances, construction tools – even your car! These rubber parts come as rings or sheets made from a soft rubber that contracts when heated so it fits snuggly.

On the other hand, rubber seals include a variety of different types. O-rings, valve stem, rotary, and mechanical seals are examples of these broader categories. They are utilized in more active applications such as motors, engines, pumps, and rotary shafts in contrast to a gasket, which is used simply for static applications.

Seals are generally flat and round, with a slanted inner rubber ring surrounded by a metal or plastic outer ring. The tilted angle of the seal’s inner layer aids in dynamic applications’ resistance to liquid leakage. They are frequently utilized to prevent leaks between two moving components, as well as to prevent particle and contaminant intrusion into the system.

Polyurethane rubber products are made up of complex molecular chains that, when formed, tend to maintain their resilience, flexibility, and shape under compression, tension, or stress. Due to urethane products’ ability to be manipulated into practically any size, shape, and hardness, it is a highly versatile material.

Here’s some key information about polyurethane rubber and how Uniflex Inc. makes sure you get the finest quality components.

Durometer (Hardness)

The “durometer” scale is used to measure the hardness of polyurethane (PU) in terms of its elasticity. A diamond-tipped hammer inside a graduated glass tube is made to fall from a certain height on the product being tested. The harder the polyurethane, the higher the rebound – the hardness number is calculated based on the height to which the hammer rebounds.

“Hardness” essentially measures the resistance of PU to indentation by three-spring-loaded indenter. The higher the durometer number, the greater the resistance.

The Rockwell hardness test or Shore durometer test are the most common ways to test the hardness of polyurethane rubber. Both tests measure its resistance toward indentation, and both provide a verifiable hardness value that doesn’t correspond to fundamental characteristics or other properties.

Durometer hardness, using either the Shore D or Shore A scale, is the widely accepted method for elastomers. The Shore D scale is used for harder polyurethanes while Shore A is used for softer ones.

The relative hardness of elastic materials like PU tends to be the Shore A hardness. If the indenter doesn’t penetrate the sample at all, a reading of 100 is obtained, and if it is able to penetrate the sample completely, the durometer reads 0.

Durometer Scales

Shore A (most common scale): Used for the majority of rubbers and elastomers

Shore OO: Used for exceptionally soft materials.

Shore D: Used for rigid plastics and other harder materials.

While a durometer is a commonly used, industry-wide indicator of other physical properties, it by no means displays the remarkable versatility of polyurethane. Depending on your unique needs, physical properties such as stretchability, flex strength, water/chemical resistance, temperature resistance, shock absorption, and rebound may be more important than hardness.

Uniflex Inc. will be happy to custom formulate your product so it has the ideal physical characteristics you want.

Other Properties of Polyurethane (PU) Elastomers

#1. Compression

In addition to high load-bearing properties in both compression and tension, PU materials have a high load-bearing capacity in shear.

#2. Abrasion

Polyurethanes are known to outperform metals, plastics, and rubber in applications where severe wear is a problem. This often means that a component made from PU can be made with lower cost, reduced maintenance, and less material.

#3. Mechanical Properties

Almost all elastomeric materials tend to bend under impact at lower hardness levels. They are compounded up to a higher degree of hardness so they end up losing their elasticity, which leads to cracks. But even at their highest hardness levels, polyurethanes have substantially better impact resistance than most plastics.

#4. Resilience

PU can be formulated in a wide range of resiliencies. If your application requires quick recovery, it can be made with rebound values from 40–70%, or it can be manufactured with rebound values of 10–25% for extreme shock-absorbing uses.

#5. Flexibility

Polyurethane rubber elastomers do not crack under continual flexing. By decreasing the thickness of the component, any cracking under heavy flexing may be reduced, which allows PU to be used even in incredibly thin sections.

#6. Temperature

Most polyurethane elastomers maintain their flexibility at very low temperatures and display excellent resistance to thermal shock. This is why PU is widely used in many applications in arctic conditions.

Polyurethanes are able to endure dramatic and sudden changes in temperature without cracking. They can also easily withstand consistent rise up to 194 F (90 C).

#7. Friction Coefficients

PU can be made with coefficients of friction ranging from really low (for parts like wear strips, bearings, and bushings) to really high (for parts like rollers and tires).

#8. Water

Polyurethanes that are polyether-based maintain their stability in water as warm as 122 F (50 C) for prolonged periods. Water absorption is extremely low at 0.3% to 1% by weight and any swell in volume is negligible. In water-lubricated applications, this allows operation at tight tolerance.
