UHMW
UHMW polyethylene is a high crystalline high density polyethylene polymer with an average molecular
weight in the 3.1 to 5.0 million range. Because of its high molecular weight, it is categorized as
Ultra High Molecular Weight polyethylene.
Products of UHMW polyethylene exhibit an exceptional combination of outstanding properties. It has
high abrasion resistance, low coefficient of friction, self-lubrication, non-adherent surface, excellent chemical fatigue
and impact resistance, and good noise dampening properties. Its outstanding characteristics include very
high resistance to wear and abrasion, and high performance at extremely low temperatures (liquid nitrogen -259 degrees C).
UHMW starts to soften and lose its abrasion resistance characteristics around 185 degrees F.
Because UHMW has a relatively high expansion/contraction rate when subjected to temperature changes,
it is not recommended for close tolerance applications in these environments.
