Polyurethanes

Polyurethane elastomers are extremely versatile materials that can be manufactured to suit individual needs to meet a range of demanding applications.

 

Polyurethane elastomers can be characterised by the following properties:

  • Hardness range of 20 shore A (gum eraser) to 80 shore D (golf ball)
  • Excellent compression properties
  • Good mechanical properties
  • High elongation
  • High tensile strength
  • Excellent tear strength
  • Exceptional resilience even in hardness grades
  • Excellent flex properties
  • Very good low temperature capabilities
  • 80║ C continuous working temperature
  • Good chemical resistance except strong acids and alkalis
  • Highly resistant to degrading from oxygen and ozone
  • Excellent sound attenuation properties
  • High coefficient of friction or grip properties


Fields of application: bushes, rollers, wheels, chute liners, conveyor rollers, oil seals, pump impellors, anti vibrations pads, timber handling components and flexible couplings.
