  • Very good wear and abrasion resistance
  • High impact strength, even at low temperatures
  • Excellent chemical resistance
  • Low density compared to other thermoplastics [≈ 1 g/cm3]
  • Low coefficient of friction
  • Excellent release properties
  • Very low water absorption
  • Moderate mechanical strength, stiffness and creep resistance
  • Very good electrical insulating and dielectric properties [except static dissipative grades]
  • Excellent machinability
  • Physiologically inert [several grades are suitable for food contact]
  • Good resistance to high energy radiation [gamma- and X-rays]
  • Not self-extinguishing [except TIVAR® Burn guard]
  • Due to UHMW-PE’s high thermal expansion and moderate resistance to creep, operating conditions should be considered when designing parts exposed to high temperatures and continuous loads.
  • Parts requiring tight tolerances should be stored away from direct heat sources on flat, supported surfaces to minimize dimensional changes.
