Ogige PVC mgbe emebere ya, na-eji plasticizers, n'ime ihe ndị na-agbanwe agbanwe, nke a na-akpọkarị PVC-P.

Ngwakọta PVC mgbe emebere ya na-enweghị plasticizer maka ngwa siri ike bụ PVC-U.

Enwere ike ichikota ngwakọta PVC dị ka ndị a:

Ngwakọta ngwakọta akọrọ nke PVC siri ike (nke a na-akpọ Resin), nke nwekwara ihe ndị ọzọ dị ka stabilizers, additives, fillers, reinforcements, and fire retardants, ga-agwakọta nke ọma n'ime igwe na-ejikọta ya.Ngwakọta na-ekesa na nkesa dị oke egwu, yana ihe niile na-akwado oke okpomọkụ akọwapụtara nke ọma.
