PVC particles are made of PVC resin powder by adding various additives, such as heat stabilizer, plasticizer, processing aids, impact modifier, lubricant, filler, etc. According to the plasticizer content in PVC particles, we can divide them into hard PVC particles and soft PVC particles, and can also divide them into injection molded PVC particles and extrusion PVC particles according to processing methods. PVC pipe particles are mostly used for PVC pipe extrusion, profile extrusion and pipe injection.

　　PVC pipe has many advantages! First, low price and high cost performance. The price of PVC pipe is much cheaper than PPR pipe, ABS pipe and PA pipe. Second, good weather resistance, PVC pipe weather resistance is relatively excellent. Third, good acid resistance, PVC pipe can withstand various concentrations of hydrochloric acid, low concentration of sulfuric acid, etc. Generally, PVC pipe particles are mainly processed by extrusion, such as PVC pipes, PVC profiles, etc., while some are processed by injection molding, such as pipe fittings, valves, etc.
