Ultra High Molecular Weight Polyethylene (UHMW)

UHMW is an exceptionally tough plastic that holds up, even after repeated impact. The abrasion resistance is extraordinary, with low friction under load. Virgin Grade UHMW is also exceptionally resistant to chemical attack including organic solvents. It's easily machined, self-lubricating and absorbs almost no water while providing high dielectric strength, but only moderate compression strength. UHMW operates safely at 160 ºF and doesn't break under IZOD impact testing.
