Polyvinyl chloride PVC resin is white powder, density is 1.35-1.46g/cm3, apparent density is 0.4-0.65g/cm3, and is insoluble in water, alcohol and gasoline. The decomposition and plasticization temperature of pure PVC resin is very close to each other. When heated to 130-140℃, it will decompose and release hydrogen chloride gas, so it is not possible to process and manufacture plastic
products with pure PVC.
