PVC-C is a new type of engineering plastic made by chlorination modification of polyvinyl chloride (PVC) resin. The product is gray or light yellow, tasteless, odorless, non-toxic loose particles or powder.

After chlorination of PVC resin, the irregularity of molecular bonds increases; polarity increases; solubility increases; chemical stability increases; heat resistance improves.

PVC-C pipes are products made of chlorinated polyvinyl chloride resin as the main raw material, with additives necessary to improve its processing performance, and are formed by extrusion (pipes) or injection molding (pipe fittings).
