What is PVC SG5？How about the application of SG5?
聚氯乙烯树脂是世界上第二大产量的原料，市场上聚氯乙烯树脂的品类众多。今天来介绍一下 SG系列。 SG代表悬浮法生产的PVC树脂，一般分1~8型，也就是SG1~SG8，SG1型分子量最大，SG8型分子量最小，硬质的PVC管材、型材等选择SG5型，注塑产品一般选SG8型，PVC软质制品一般选择SG4型或以下。
PVC resin is the second largest raw material in the world, and there are many kinds of PVC resin on the market. Today, let's introduce the SG series. SG represents the PVC resin produced by suspension method, which is generally divided into 1~8 types, that is, SG1~SG8, SG1 has the largest molecular weight, and SG8 has the smallest molecular weight. SG5 type can be used for rigid PVC pipes and profiles, SG8 type is generally selected for injection molding products, and SG1-SG4 type is generally selected for PVC soft products.
