GUR® ultra-high molecular weight polyethylene (UHMW-PE) is a linear polyethylene with a much higher molecular weight than standard PE, which offers outstanding abrasion resistance, superior impact resistance, non-sticking and self-lubricating properties, and excellent mechanical characteristics, even in cryogenic conditions.
As a polyethylene with a very high molecular weight, GUR® UHMW-PE is produced as a powder that requires special processing. In the semi-finished industry, the high pressures generated in compression molding and ram extrusion processes fuse the particles together. The material is then typically formed into stock shapes or profiles. It can also be processed by gelation and pressureless sintering.
GUR® UHMW-PE premium grades for orthopedic implants and standard grades meet the requirements of heath organizations, such as the U.S. Food and Drug Administration (FDA) and European Union food-conformity. FDA Drug and Device Master Files are available for premium grades.
