Service life of ultra high molecular weight polyethylene(UHMW-PE) is higher than that of steel. Its wear resistance is 4-7 times that of the carbon steel and stainless steel. UHMW-PE has the characteristics of small friction coefficient, self lubrication, no water absorption, no bonding materials, high intensity of impact resistance, good mechanical properties, acid-, alkali-, salt-corrosion resistance, good anti-aging properties, low temperature resistance, healthy, non-toxic, light weight and the proportion of 1/8 of the steel. Therefore, it is the best material for the lining of equipment for storing and transporting bulk materials, such as storage bin, launder; and it is widely applied in electric power, steel mill, coal mine and other industries.
