Amabhizinisi amakhulu asekhaya akhiqiza i-PVC e-calcium carbide akhuthaza ngamandla isu lokuthuthukiswa komnotho ojikelezayo, andise futhi aqinise uchungechunge lwezimboni nge-calcium carbide PVC njengesisekelo, futhi alwela ukwakha iqembu elikhulu lezimboni elihlanganisa "usawoti wamalahle-ugesi-usawoti". Njengamanje, imithombo yemikhiqizo ye-vinyl vinyl eShayina ithuthuka ngendlela ehlukahlukene, okuvule nendlela entsha yokuthengwa kwezinto zokusetshenziswa embonini ye-PVC. Amalahle asekhaya-kuya-olefins, i-methanol-kuya-olefins, i-ethane-kuya-ethylene nezinye izinqubo zesimanje zenze ukuhlinzekwa kwe-ethylene kwaba kuningi kakhulu.
