Zhongtai PVC Sg3 Resin K71-K72 Polyvinyl Chloride

Product Description

PVC resin is a polymer compound formed by polymerization of vinyl chloride monomer (VCM), and its structure unit is [CH2-CHCL]n. polymerization degree is usually 590-1500. According to the content of residual polyethylene monomer in PVC resin can be divided into: industrial grade, food hygiene grade, medical grade three. The appearance of PVC resin is white powder.
