UHMWPE is used as a new type of non-metallic materials, ultra-high molecular weight polyethylene, a molecular weight of 1 million or more polyethylene. Ultra high molecular weight polyethylene liner electricity: ultra high molecular weight polyethylene liner widely used in electric power, steel, coal and other industries. Currently UHMWPE products are plate type, pipe, bar class and finished products, imported ultra-high molecular weight polyethylene, which finished products including gears, bearings, bushings, rollers, rails, sliders, and a variety of products. Ultrahigh molecular weight polyethylene liner is more than one million molecular weight polyethylene. Formula: - (- CH2-CH2 -) - n-, ultra high molecular weight polyethylene wear, density: 0.936 ~ 0.964g / cm3. Heat distortion temperature (0.46MPa) 85 ℃, m.p. 130 ~ 136 ℃. Ultrahigh molecular weight polyethylene liner product development: With the development of ultra-high molecular weight polyethylene processing technology, and its products have been successfully applied in many fields.
