UHMWPE is used as a new type of non-metallic materials, a molecular weight of 1 million or more polyethylene. Ultra high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering plastic with excellent overall performance of a linear structure. It combines the advantages of most plastics can be ultra high molecular weight polyethylene wear block, impact resistance, low temperature resistance, abrasion resistance, chemical resistance, self-lubricating, high-impact energy absorbing ultra high molecular weight polyethylene wear blocks, six characteristic is the highest value plastic has. UHMWPE is used as a new type of non-metallic materials, a molecular weight of 1 million or more polyethylene. Ultrahigh molecular weight polyethylene liner high wear resistance: in all current engineering plastics in the best wear resistance of UHMW-PE, the most striking. The higher molecular weight of the material, the more wear-resistant, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.).
