Polyethylene wax in the process of filling masterbatch mainly plays a lubricating role, can effectively solve the precipitation phenomenon of filling masterbatches, can significantly improve the surface gloss of the product. PE wax can also effectively improve the physical properties in the process of filling masterbatch, and also improve the toughness. Advantages of PE wax for filling masterbatch 1, Excellent lubricity, cold resistance, heat resistance, chemical resistance and wear resistance. With low viscosity and high softening point. Good hardness, good thermal stability, low volatility at high temperature and other properties. As a lubricant, its chemical properties are stable and its electrical properties are good. 2, Improve the surface gloss, and have excellent dispersion of pigments. As an additive can be directly added to polyolefin processing, it can increase the gloss. 3, Improve extrusion efficiency. Greatly improve the fluidity of the process, and increase the extrusion efficiency of the products. 4, Improve the melting property and prevent the frost spraying phenomenon. Reduce the bad phenomenon of product surface. Reduce the melt breakage during plastic processing, reduce the irregularity of film surface and frost spraying phenomenon due to excessive pressure. Because of the low viscosity and good compatibility with pigments, polyethylene wax is easier to wet pigments and penetrate into the internal pores of pigment agglomerates, weakening the cohesion, making it easier for pigment agglomerates to open under external shear, and new particles can be quickly wetted and protected. In addition, polyethylene wax can play a role in reducing the viscosity of the system and improving the fluidity, so the addition of polyethylene wax in the production of masterbatch can improve the production efficiency.
