PVC is a linear thermoplastic resin produced by polymerization of vinylchlo ride monomer. Due to the difference of raw materials, there are two methods of synthesizing vinylchlo ride monomer - calciumcarbide process and petroleum process. The product has good chemical corrosion resistance, excellent electrical insulation property and fine chemical stability. With high chlorinecontent, the material has good fire retardance and self-extinguishing properties. PVC is easy to process by extrusion, injection molding, calendering, blow molding, compressing, cast moulding and thermal molding, etc.
