Polyurethane

Polyurethane elastomers are one of the most versatile materials available for the manufacturing of modern engineering products. They offer the client a unique combination of hardness, resilience and durability.

Properties of Polyurethane

  • Excellent resilience to oils, fuels and many other chemicals
  • Exceptional abrasion and erosion resilience and will out-perform even hardened steel
  • Excellent tensile strength makes polyurethane more resistant to tears and cuts than rubbers or silicone
  • Polyurethane has excellent load bearing properties in compression and tension
  • Very good versatility at low temperatures between -40°c to +80°c
  • Hard polyurethane has excellent machining capabilities and these components would stand up against all type of metals
  • Exceptional hardness ranges from the softest rubber up to the hard plastics & metal materials, see below:

If you specify a product and its application, there is probably a polyurethane to suit.
