Polyvinyl chloride (ka mokhoa o mong: poly(vinyl chloride), colloquial: polyvinyl, kapa vinyl feela; khutsufatso ea: PVC) ke polymer ea maiketsetso ea polasetiki ea boraro lefatšeng ka bophara (kamora polyethylene le polypropylene).Ho hlahisoa lithane tse ka bang limilione tse 40 tsa PVC selemo le selemo.
PVC e tla ka mefuta e 'meli ea motheo: e thata (ka linako tse ling e khutsufatsoa e le RPVC) le ho tenyetseha.Mofuta o thata oa PVC o sebelisoa kahong ea liphaephe le lits'ebetsong tsa profil joalo ka mamati le lifensetere.E boetse e sebelisoa ho etsa libotlolo tsa polasetiki, liphutheloana tseo e seng tsa lijo, maqephe a koahelang lijo le likarete tsa polasetiki (joalo ka likarete tsa banka kapa tsa litho).E ka etsoa hore e be bonolo 'me e be bonolo haholoanyane ka ho eketsoa ha li-plasticizers, tse sebelisoang ka ho fetisisa ke phthalates.Ka foromo ena, e boetse e sebelisoa ho kenya liphaephe tsa metsi, ho kenya lithapo tsa motlakase, letlalo la ho etsisa, fatše, matšoao, lirekoto tsa keramafono, lihlahisoa tse fofang, le lisebelisoa tse ngata moo e nkelang rabara sebaka.Ka k'hothone kapa line, e sebelisoa ho hlahisa seile.
