Polyethylene wax (PE wax), also known as polymer wax, 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 part of the wax can be added directly to the polyolefin processing as an additive, which can increase the gloss and processability of the product. As a lubricant, it is chemically stable and has good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene and ABS and the release of polymethyl methacrylate and polycarbonate. Compared to PVC and other external lubricants, polyethylene wax has a stronger internal lubricating effect.
