UHMW (Ultra-High-Molecular-Weight Polyethylene)
UHMW offers a combination of exceptional properties. It is tough with superior impact strength. It is corrosion-resistant and exhibits virtually no water absorption. It is also wear-resistant, non-sticking and self-lubricating.
UHMW is an excellent choice for many industrial applications. It reduces noise and vibration, is chemical-resistant and non-toxic and offers excellent mechanical properties even in cryogenic conditions.
