I-PVC iwuhlobo lwepulasitiki olusetshenziswa kabanzi ezintweni zokwakha. Ngakho-ke, ngeke ithathelwe indawo isikhathi eside esikhathini esizayo, futhi izoba nethuba elihle lokufaka isicelo ezindaweni ezingathuthukisiwe esikhathini esizayo.
Njengoba sonke sazi, kunezindlela ezimbili zokukhiqiza i-PVC, enye iyindlela evamile yomhlaba wonke ye-ethylene, kanti enye iyindlela eyingqayizivele ye-calcium carbide e-China. Imithombo yendlela ye-ethylene ikakhulukazi i-petroleum, kanti imithombo yendlela ye-calcium carbide ikakhulukazi amalahle, i-limestone nosawoti. Lezi zinsiza zigxile kakhulu eShayina. Isikhathi eside, indlela yaseChina ye-PVC ye-calcium carbide ibilokhu isendaweni ehamba phambili ngokuphelele. Ikakhulukazi kusukela ngo-2008 kuya ku-2014, amandla okukhiqiza e-PVC e-calcium ye-calcium carbide ayekhula, kodwa futhi ilethe izinkinga eziningi zokuvikela imvelo.
