Polyvinyl chloride (PVC) nimwe mubintu bikunze gukoreshwa muri polymeki yisi (kuruhande rwabashe na plastike ikoreshwa cyane nka pet na pp). Numuzungu usanzwe kandi utontoma (mbere yo kongeramo plastistizers) plastiki. PVC yabaye hirya no hino kuruta phostics nyinshi zimaze kubanza mu 1872 kandi zikorwa mu bucuruzi na bf Goodrich sosiyete ya BF muri 1920. Mugereranije, izindi phostique nyinshi zisanzwe zashyizwemo mbere kandi zimenyerewe mubucuruzi gusa mu myaka ya za 1940 na 1950. Ikoreshwa cyane mu nganda zubwubatsi ariko nazo zikoreshwa mubimenyetso, gusaba ubuvuzi, na fibre yimyenda.
PVC ikorwa muburyo bubiri rusange, ubanza nkumukaramunite cyangwa umuzimuco (RPVC cyangwa UPVC), na kabiri nka plastike yoroshye. Byoroshye, pVC cyangwa PVC isanzwe yabyoroshye kandi ihanishwa no kunama kuruta UPVC kubera ko hiyongereyeho plastistizers nka plaphalate cyangwa disp). PVC ihindagurika ikoreshwa mubwubatsi nkuko insikulation ku nkinga z'amashanyarazi cyangwa mu bitaro, amashuri, amashuri, ndetse no mu bindi bidukikije ari byo imbere, kandi rimwe na rimwe nko gusimbuza reberi.
Rigid PVC ikoreshwa kandi mubwubatsi nkumuyoboro wo kumazi no kugikunze kuvugwa nijambo "vinyl" muri Amerika. Umuyoboro wa PVC usanga usanganijwe na "urugero" (urugero kuri 40 cyangwa gahunda 80). Itandukaniro rikomeye hagati ya gahunda ririmo ibintu nkibyinshi cyane, igipimo cyigitutu, namabara.
Bimwe mubiranga PVC byingenzi birimo igiciro gito ugereranije, kurwanya imiti na chimique na alkalies), ubukana buhebuje, imbaraga zidasanzwe kuri plastiki pvc ya Rigid. Birahari cyane, bikunze gukoreshwa kandi byoroshye gukoreshwa (byashyizwe mubikorwa kode yo kumenyekanisha resin "3").
