Polyvinyl chloride (PVC) waa polymer lagu sameeyay vinyl chloride monomer (VCM) oo ku jira peroxide, azo compound iyo hindiseyaal kale ama sida ku cad habka polymerization xagjirka ah ee bilaashka ah ee hoos yimaada ficilka iftiinka iyo kuleylka.Vinyl chloride homopolymer iyo vinyl chloride copolymer ayaa si wada jir ah loogu tilmaamaa xabagta vinyl chloride.
PVC waxay mar ahaan jirtay balaastiigga ugu weyn adduunka, taas oo si weyn loo isticmaali jiray.Waxaa si ballaaran loo isticmaalaa qalabka dhismaha, alaabta warshadaha, waxyaabaha maalinlaha ah, maqaarka sagxadda, foornada sagxadda, maqaarka macmalka ah, tuubooyinka, fiilooyinka iyo fiilooyinka, filimka baakadaha, dhalooyinka, alaabta xumbo, alaabta wax lagu xiro, fiilooyinka iyo wixii la mid ah.
Marka loo eego baaxadda dalabka ee kala duwan, PVC waxaa loo qaybin karaa: xuubka PVC-ga guud, heerka sare ee polymerization-ka PVC-ga iyo resin-ka-xiran ee PVC.Ujeedada guud ee xabagta PVC waxaa lagu sameeyay polymerization of vinyl chloride monomer iyadoo hoos timaada ficilka bilawga;Darajada polymerization-ka sare ee xabagta PVC waxaa loola jeedaa xabagta polymerized iyadoo lagu darayo wakiilka koritaanka silsiladda ee nidaamka polymerization vinyl chloride monomer;Xabagta PVC ee isku xidhan waa resin polymerized iyadoo lagu darayo walax isku xidha oo ka kooban diene iyo polyene nidaamka polymerization vinyl chloride monomer.
Marka loo eego habka loo helo monomer vinyl chloride monomer, waxaa loo qaybin karaa habka calcium carbide, habka ethylene iyo soo dejinta (EDC, VCM) habka monomer (caado ahaan, habka ethylene iyo habka monomer dibadda laga keeno ayaa si wadajir ah loo tixraacaa habka ethylene).
