The higher the molecular weight of high molecular weight polyethylene, the higher the wear resistance, and even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.). For example, UHMWPE-PE pipe has a service life of 4-6 times that of steel pipe under strong corrosion and high wear conditions, and improves the conveying efficiency by 20%. It fully demonstrates the advantages of "energy saving, environmental protection, economy and high efficiency".
Corrosion resistance: It is not corroded in lye, can be used in concentrated hydrochloric acid at 80°C, and has stable performance in 75% concentrated sulfuric acid and 20% nitric acid. It is also stable to seawater and liquid detergents. Extremely low coefficient of friction: the coefficient of static friction is 0.07, and the self-lubricating property is good. It is an ideal material for bearings, bushings, sliders and linings. Selecting UHMWPE as the friction part of the equipment can not only improve the wear-resistant life, but also save energy.
