About Urethane
Polyurethane: Strong. Tough. Durable. Versatile.
What problems do you have that urethane can solve? Do you face high-impact operations... or intense load bearing applications ... or harsh environments? PSI Urethanes, Inc.'s products can solve these problems and many more. We are the world's leading supplier of urethane products that are stronger, tougher, more durable, and more versatile than any conventional elastomers and plastics available today.
Our products are scientifically formulated to be more resistant to abrasion, cracking, tearing, heavy loads, high impact, harsh environments, and more. In fact, when you use urethane you may never have to replace a worn out part again. That's why smart companies in hundreds of industries around the world use PSI Urethanes' polyurethane products for their critical business applications.
7 Reasons Why You Can Count on Urethane Products from PSI Urethanes
Take a look at all of the advantages you'll gain when you choose urethane products from PSI Urethanes:
- Wide Range of Hardness
- Abrasion and Impact Resistant
- Higher Load Bearing and Flexing Capacity
- High or Low Friction Variability
- Strong Bonding Properties
- Stable in Harsh Environments
- Wide Resiliency Range
Durometer - Wide Range of Hardnesses
We can formulate urethanes in a wide range of durometers (hardness) from bowling ball hard (70 on the D scale), as well as, full A scale, to marshmallow soft (below 10 on the "00" scale).
Abrasion and Impact Resistant
Urethane resists abrasion and holds up in high-impact applications.
- Abrasion resistant. When resistance to abrasion is critical, our high performance urethane products stay on the job. In fact, our urethane products often outwear other materials from five-to-one to fifty-to-one when severe abrasion is a factor.
- Impact resistant. Are your parts subject to high impact or repeated impingement? Our urethane products remain elastic even in the hardest formulations.
Higher Load Bearing and Flexing Capacity
- High Load Bearing Properties. Urethane parts formulated by PSI Urethanes have higher load-bearing capacity than any conventional rubber. This makes urethane ideal for items such as high load-bearing wheels, heavy-duty couplings, metal forming pads, shock pads, and machine mounts.
- High Flex Properties. Our urethanes make great hinges and diaphragms. Because of the inherent strength and toughness of our precision cast urethane, we can make parts extremely thin at the flex point, which greatly reduces the risk of cracking that comes with thicker parts made of other elastomers.
High or Low Friction Variability
Friction against non-lubricated surfaces generally decreases with harder formulation and increases with softer formulations. We can formulate urethanes with low coefficients of friction for a variety of surface types.
Strong Bonding Properties
Our urethane can be bonded to a wide range of materials during or after the molding process. Bonds on metal, wood, and plastic substrates are especially strong. In addition, our precision cast sheets can be manufactured without the use of mold-release or a wax base. Unlike other manufacturing processes that run the sheets through a secondary cleaning operation before bonding, our sheets go through a special process that allows them to stay mold-release-free (or wax-free). This technical advancement ensures an end product with even greater bonding properties than ever before.
Stable in Harsh Environments.
- Harsh environments are no contest for our urethane products. Our sheets, pads, rollers, tubes, rings, and more stand up to temperature extremes and exposure to water, ozone, oxygen, oil, grease, and chemicals.
- Flexible at low temperatures. We can formulate urethanes to remain flexible in Arctic-like conditions or through sudden drops in temperature.
- Stable up to 250° F. Our experts can formulate urethanes to withstand continuous use up to 200° to 250° F.
- No swelling or deterioration in water. Our urethanes remain stable even when immersed in water as warm as 120° F for very long periods. (Although we don't recommend continuous use in water hotter than 180° F.) Our precision-cast sheets, pads, rollers, tubes, rings, and other products absorb practically no water: approximately 0.3 to 1.0 percent by weight with negligible volume swell even after prolonged immersion.
- Electrical conductivity control. Customers frequently request our urethanes because of urethane's excellent insulating properties. We can increase electrical conductivity to suit your needs.
- Resistant to ozone and oxygen. Our urethanes are virtually immune from attack by ozone and oxygen. Therefore, they're the ideal performer around electrical equipment without the cracking and hardening associated with conventional elastomers and plastics.
- Resistant to oil, grease, and chemicals. Our urethanes resist a wider range of chemicals and substances than most rubbers and plastics. They perform well under contact with solvents, oils, and chemicals.
Wide Resiliency Range
Unlike rubber, our products don't have to be soft to be resilient. In fact, our urethanes can be as resilient as much softer materials. For shock absorbing applications, our urethanes can be formulated with rebound values as low as 10% or 25%. For quicker recovery or where high-frequency vibrations are a factor rebound values of up to 40% to 70% can be formulated.
