Polyurethane materials and formulations
We formulate and cast polyurethane compounds tailored to your specific wear, impact, and operating conditions. From soft shock-absorbing compounds to hard abrasion-resistant formulations, every material is selected based on the application.
Polyurethane property overview
Typical ranges across our polyurethane formulations and a comparison with rubber, steel and UHMW for the same wear, impact and operating conditions.
Polyurethane property overview
| Property | Typical range |
|---|---|
| Shore hardness range | 60A–75D |
| Tensile strength | 3,000–8,000 psi |
| Abrasion resistance | Very high (superior to rubber and UHMW) |
| Temperature range | -40°C to +80°C |
| Rebound / resilience | Moderate to high |
| Oil and water resistance | Yes |
| Metal bonding | Chemical bond to steel, aluminum, stainless |
Polyurethane vs rubber vs steel vs UHMW
| Material | Abrasion | Impact damping | Weight | Best for |
|---|---|---|---|---|
| Polyurethane | Excellent | Excellent | Light–medium | Wear parts, rollers, seals, liners |
| Rubber | Moderate | Good | Low | Short-life or low-cost replacements |
| Steel | High | Poor | Heavy, noisy | Extreme impact only |
| UHMW | Low | Low | Light | Low-wear sliding surfaces only |
Custom formulations for your application
Every application has different requirements. We adjust shore hardness, rebound, chemical resistance, and other properties to match your operating conditions. Our formulations include TDI ethers and esters, MDI ethers and esters, and specialty compounds for high-heat or chemical exposure.
We also work with NBR (Nitrile Butadiene Rubber) and Viton for applications where these materials are a better fit.
Additives available

Questions about polyurethane materials
-
What shore hardness do I need?
Softer compounds (60A–80A) are better for impact absorption, noise reduction, and flexibility. Harder compounds (90A–75D) are better for abrasion resistance and cut resistance. Our engineers recommend based on your application. -
Can you match a competitor’s formulation?
In most cases, yes. Send us a sample or the material data sheet and we can formulate an equivalent or improved compound. -
Do you provide material data sheets?
Yes. Technical data sheets are available for all our standard formulations. For custom compounds, we provide full property documentation after testing.
