Saboda kayan aiki na PVC suna dacewa sosai tare da PVC kuma suna da nauyin nauyin kwayoyin halitta mai girma (kimanin (1-2) × 105-2.5 × 106g / mol) kuma babu foda mai rufi, suna ƙarƙashin zafi da haɗuwa a lokacin aikin gyaran gyare-gyare. Suna fara laushi kuma suna ɗaure ɓangarorin guduro da ke kewaye. Ta hanyar juzu'i da canja wurin zafi, ana haɓaka narkewa (gel). Danko na narkewa baya raguwa, ko ma karuwa; Saboda ƙulla sarƙoƙin ƙwayoyin cuta, an inganta elasticity, ƙarfi, da haɓakar PVC.
Bugu da ƙari, saboda gaskiyar cewa sassan da ba su dace da juna ba na PVC sun haɗa da kayan aiki na kayan aiki tare da tsarin harsashi mai mahimmanci.
