Double wall corrugated pipe stiffening masterbatch is an excellent plastic modified filler, mainly composed of high-purity black talc powder, which is granulated by twin screw extrusion and blended with carrier PP or PE. The system has good modification effect, good processing performance, large addition amount, no moisture absorption, and no discoloration. It has water resistance, chemical corrosion resistance, and light resistance. It does not have harmful chemical reactions with other plastic additives, and does not contain impurities harmful to resin processing. Features of this product: 1. It can significantly improve the stiffness and strength of pipes, meet the requirements of Grade 8 pipes in the national standard, and meet the engineering design requirements 2. It can reduce the weight of pipes and has a light specific gravity. 3.Due to the presence of certain additives in the pipe, it can improve processing performance and increase the stability of the melt.
