Polyurethane

Polyurethane is used mainly for flexible seals, which are tough and will not have to withstand any temperature extremes or water. Polyurethane is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. Because urethane is available in a very broad hardness range (eraser-soft to bowling-ball-hard), it allows the engineer to replace rubber, plastic and metal with the ultimate in abrasion resistance and physical properties. Polyurethane can reduce plant maintenance and OEM product cost.

Urethanes have better abrasion and tear resistance than rubbers, whist offering higher load bearing capacity. Many applications using this ultra-tough material have reduced down-time, maintenance time and cost of parts to a fraction of their previous figures.

Urethanes have replaced metals in sleeve bearings, wear plates, sprockets, rollers and various other parts, with benefits such as weight reduction, noise abatement and wear improvements.

Benefits of Polyurethane:

  • Tough
  • Strong
  • Abrasive resistant
  • Not as toxic as EPDM or Fluorocarbon
  • Load bearing capacity
  • Tear resistant. The tear-strength ranges between 500-100 Ibs / linear inch, which is far superior to rubbers. · Weather resistant -to oxygen, ozone, sunlight and general weather conditions.
  • Excellent noise abatement properties
  • Improved sound/vibration dampening
  • Flex-Life – excellent elastic memory
  • Excellent electrical insulating properties
  • Heat and cold resistant - Continuous use above 110°C (225°F) is not recommended nor is urethane recommended in hot water over 80°C (175°F). At low temperatures, polyurethane will remain flexible down to -68°C (-90°F). A gradual stiffening will occur at -18°C (0°F), but will not become pronounced until much lower temperatures are obtained
