Polyvinyl chloride (PVC), oo loo yaqaan PVC, waa polymer-ka badan ee loo isticmaalo warshado kala duwan. Waxaa lagu soo saaraa polymerization vinyl chloride monomer (VCM) iyada oo loo marayo habka polymerization-ka bilaashka ah iyadoo la kaashanayo peroxides, xeryahooda azo ama kuwa kale ee bilaabay, iyo sidoo kale iftiinka iyo kulaylka. PVC waxaa ka mid ah vinyl chloride homopolymers iyo vinyl chloride copolymers, oo si wada jir ah loogu yeero vinyl chloride resins. Iyada oo leh sifooyinkeeda cajiibka ah iyo la qabsiga, PVC waxay noqotay agabka doorashada ee codsiyo badan.
