performance

Extremely high wear resistance: it is very valuable in engineering application, the ratio of carbon steel, stainless steel, bronze new wear-resisting of even higher.

High shock resistance: molecular weight reached its peak value in 2 million, more than 2 million will gradually decline.

Extremely low coefficient of friction: ultra-high molecular weight polyethylene is very wear-resisting, and low friction coefficient, good self-lubrication, is an ideal bearing bushings, slider, lining material. The use of ultra-high molecular weight polyethylene as friction parts of equipment, besides can improve the wear life, energy saving effect can be received.

Low temperature resistance: because of ultra-high molecular weight polyethylene is an excellent material toughness, and its low resistance is also very good, in - 269 °C, low temperature, still have certain ductility, and shows no sign of embrittlement.
