[0002] Polyethylene wax (PE wax), also known as polymer wax or simply polyethylene wax, is widely used due to its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this part of the wax can be directly added to the polyolefin processing as an additive. It can increase the gloss and processing performance of the product. As a lubricant, its chemical properties are stable and its electrical properties are good. Polyethylene wax has good solubility with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene and ABS and the demoulding properties of polymethyl methacrylate and polycarbonate.
