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 and medical grade. The appearance of PVC resin is white powder. PVC resin SG3 SG5 SG8 is flame-retardant (flame retardant value above 40), high chemical resistance (resistant to concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid and 20% sodium hydroxide), mechanical strength And the advantages of good electrical insulation. But its heat resistance is poor, with a softening point of 80�°C, it starts to decompose and change color at 130�°C, and precipitate HCI. Application: It is widely used in the production of polyvinyl chloride boardy leatheroid, paint and adhesive agents, paint and adhesive. Packing: 25kgs two layers draft paper bag or 1000kgs PP bag.
