UHMWPE guide rail is made of UHMWPE material which has exceptionally low coefficient of friction offering superb sliding properties and is one of the best plastics for wear/abrasion resistance meanwhile tough and impact resistant even at cryogenic temperatures. As a result, it is definite that UHMW polyethylene is a wonderful engineering plastic that can solve many problems that other engineering plastics cannot.
Advantage of UHMWPE plastic chain guides/plastic guide rails/Guides for roller chains:
UHMW exhibits virtually no water absorption
Low coefficient of friction Corrosion resistant
Abrasion and impact resistant
