Material Notes:
The ultra high molecular weight Polyethylene has a high abrasion resistance and a high toughness at the same time. The chemical and the crack resistance are optimized in comparison to the standard PE-HD. The operating temperature if PE-UHMW is -150°C to 90°CProperties:low densityhigh toughnesshigh elongationvery good electrical and dielectric propertiesvery low water absorptionlow steam permeabilityhigh chemical resistancegood protection against stress crackingfood safesoft surfaceHF welding not recommendednatural color is not weather resistanceApplicationspumping and valve partsgasketsglide profilesfood industry parts
