PP highly filled masterbatch is made of PP as carrier, after surface activation treatment, with dispersant and other special processing aids, after mixing and extruder extrusion. Masterbatch plasticity is good, can improve the surface rigidity of PP products, and can greatly increase the heat-resistant temperature of PP products, improve the smoothness, improve surface gloss, acid resistance, alkali resistance, high temperature resistance, non-toxic, odourless, high strength and easy to disperse the characteristics of good fluidity, is an important raw material for engineering plastics, sheet, pallet, high-grade automobile parts, automobile bumper and various types of injection heat-resistant appliance shells, sanitary ware and other important raw materials. The high additive quantity greatly reduces the cost of finished products. Adding proportion: 10~30%, it can improve the performance of injection moulding products.
