When Total Sealing Is a Must

PE-UHMW is an ultrahigh-molecular-weight polyethylene with an extremely high molar mass. The material can be processed by extrusion or pressing, primarily to produce seals and/or engineered parts. PE-UHMW is characterized by the following outstanding properties:

  • Very good wear and abrasion resistance, even with abrasive media
  • Excellent chemical resistance
  • Low friction coefficient and, consequently, good sliding characteristics
  • Outstanding dimensional stability and therefore suitable for high pressures
  • Very low water absorption
  • High impact strength, even at low temperatures
  • Very good electrical insulation properties
  • Ideal properties for use in applications involving water
  • Usable in the food and pharmaceutical industries
  • Operating temperatures up to max. +100°C
  • Very low gas permeability

This property profile makes PE-UHMW the ideal material for use in continuous direct contact with water. It is also approved for use in the food and pharmaceutical industries. Typical components made from PE-UHMW include piston and rod seals, such as spring-energized seals or Elring memory packings.

Using special compounds based on PE-UHMW and PTFE allows a targeted improvement in the plastic’s sliding characteristics and thus a reduction in friction.
