Polyethylene wax (PE wax), also known as polymer wax for short polyethylene wax. Because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance, it is widely used. In normal production, this part of the wax can be directly added to the polyolefin processing as an additive, which can increase the luster and processing properties of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax is soluble in polyethylene, polypropylene, polyvinyl acetate, ethylene-propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene and ABS and the release property of polymethyl methacrylate and polycarbonate. For PVC and other external lubricants, polyethylene wax has a stronger internal lubrication effect, can be used as its lubricant in extrusion, calender, injection processing.
