Description:
Ultra High Molecular Weight (UHMW) Polyethylene
is often referred to as the world’s toughest polymer. UHMW PE is a linear high density polyethylene which has high abrasion
resistance as well as high impact strength. UHMW PE is also chemical resistant and has a low coefficient of friction which make it highly effective in a variety of applications.
