Saboda kayan aikin sarrafa PVC suna da matuƙar dacewa da PVC kuma suna da babban nauyin kwayoyin halitta (kimanin (1-2) × 105-2.5 × 106g/mol) kuma babu foda mai rufi, suna fuskantar zafi da haɗuwa yayin aikin ƙera su. Da farko suna laushi kuma suna ɗaure ƙwayoyin resin da ke kewaye da su sosai. Ta hanyar gogayya da canja wurin zafi, narkewa (gel) yana ƙaruwa. Danko na narkewar ba ya raguwa, ko ma ya ƙaru; Saboda haɗa sarƙoƙin kwayoyin halitta, an inganta sassauci, ƙarfi, da kuma faɗaɗa PVC.
Bugu da ƙari, saboda gaskiyar cewa sassan PVC masu jituwa da marasa jituwa suna samar da kayan aiki na sarrafawa tare da tsarin harsashi na tsakiya. Gabaɗaya, bai dace da PVC ba don haka yana aiki azaman mai shafawa na waje, amma baya haifar da sikeli kuma yana samar da sikeli, wanda ke da tasiri na jinkiri akan narkewa. Saboda haka, bisa ga waɗannan halayen aikace-aikacen, ana iya raba kayan aikin sarrafa PVC zuwa rukuni biyu: na duniya da mai shafawa.
