Ultra high molecular weight polyethylene sheet is engineering thermoplastics. It combines the superior performance of most plastics, impact resistance, low temperature resistance, abrasion resistance, chemical resistance, self-lubricating, absorb impact energy polyethylene coal bin liner material processing, which is the six characteristics of the plastic the highest value has, in recent years, this new type of plastic widely used in Europe and the United States, demand is growing. Self-lubricating UHMWPE extruded: external lubricant mainly higher fatty acids, complex lipids, silicone resin, paraffin and other low molecular weight resins. Prior to extrusion (injection) processing Buy polyethylene coal bin liner material, the first lubricant mixed together with other processing aids material in polyethylene coal bin liner material plant, production time, material lubricant infiltration out, form a lubricating layer, to achieve self-lubricating extrusion (injection).
