Polyethylene wax (PE wax), also known as polymer wax, is referred to as polyethylene wax. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this wax can be directly added to polyolefin processing as an additive, which can increase the luster and processing performance of the product. As a lubricant, its chemical properties are stable and its electrical properties are good. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene, ABS and the demoulding property of polymethyl methacrylate and polycarbonate. For PVC and other external lubricants, polyethylene wax has a stronger internal lubrication effect.
