UHWM Characteristics

UHMW (ultra-high-molecular-weight polyethylene) offers a combination of exceptional properties. This thermoplastic material is tough with superior impact strength. It is corrosion-resistant and exhibits virtually no water absorption. It is also wear-resistant, non-sticking and self-lubricating.

UHMW is an excellent choice for many industrial applications. It reduces noise and vibration, is chemical-resistant and non-toxic and offers excellent mechanical properties even in cryogenic conditions. Characteristics include:

  • Non-toxichere to help 200
  • Low coefficient of friction
  • Corrosion, abrasion, wear and impact resistant
  • Extremely low water absorption
  • FDA and USDA approved

Applications for UHMW Thermoplastic

  • Chute linings
  • Food processing parts
  • Chemical tanks
  • Conveyor guides
  • Wear pads
