UHMW Machining

UHMW Machined Parts

Ultra-high-molecular-weight polyethylene (UHMW) machined part example

Meets L-P-390.

Ultra High molecular weight polyethylene, or UHMW, as it is commonly known, is a high crystalline high density polyethylene polymer with a median molecular weight that falls within the range of 3.1 to 5.0 million.

Parts machined from UHMW polyethylene showcase an exceptional combination of outstanding properties. High abrasion resistance, low coefficient of friction, self-lubrication, non-adherent surface, excellent chemical fatigue, impact resistance, ease of machinability, and good noise dampening properties, are all inclusive of UHMW. Its outstanding characteristics embrace very high resistance to wear and abrasion, and high performance at extraordinarily low temperatures (i.e. liquid nitrogen -259 degrees C). Only when temperatures reach 185 degrees F, will UHMW start to soften and lose its abrasion resistance characteristics.

Because UHMW features a comparatively high expansion and contraction rate once subjected to temperature changes, it\'s not suggested for close tolerance applications in these environments

However, custom UHMW machining to close fabrication tolerances is easily achieved through Vanderveer Industrial Plastics' CNC machining abilities.
