PVC is polymerized from vinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging and acid and alkali resistance, so it is very suitable for the use of chemical pipelines. PVC (PolyVinylChloride) generally has 7 grades (SG1-SG7) according to the hardness and performance of the material, and the density is about 1.4g/cm. The products below SG4 are generally soft products, and a large amount of plasticizer needs to be added during molding. They are mainly used to make artificial leather, wire and cable insulation layers, seals, etc.
