Polyethylene wax (PE wax), also known as polymer wax, is referred to as polyethylene wax. Polyethylene wax (PE wax) is a low molecular weight polyethylene with an average relative molecular weight of 1000~2500, which can be made from ethylene through high pressure or low pressure polymerization, or through the controllable pyrolysis of high molecular weight polyethylene. The density of PE wax (0.92~0.94G/CM) prepared by high-pressure polymerization of ethylene ³) And softening point (85~115 ℃) are low, while the density of PE wax produced by ethylene polymerization under low pressure is 0.94~0.97G/CM ³) And softening point (125~140 ℃). PE wax has stable chemical properties, excellent electrical properties, and has the same PVC lubricity as paraffin wax, but is sensitive to the dosage. Its molecular distribution is very special, and it has a unique molecular structure, which is not as easy to disperse as the molecular structure of oiled wax, so it also has a typical special effect of high hardness even at high temperatures. Polyethylene wax can be dissolved in all waxes and most resins, and has an ideal blending effect, especially for resin rubber. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In production, this wax can be directly added to the processing of PVC products as an additive, which can increase the luster and processing performance of the products. As a lubricant, its chemical properties are stable and its electrical properties are good. Polyethylene wax has good compatibility with PVC resin powder. It can improve the demoulding property of products. For PVC and other external lubricants, polyethylene wax has a stronger internal lubrication effect
