Zvinoenderana nenhamba muna 2020, huwandu hwepasi rose hwekugadzira PVC hwasvika 62 miriyoni matani uye iyo yakazara yakabuda yakasvika 54 miriyoni matani.Kudzikiswa kwese kwekubuda kunoreva kuti huwandu hwekugadzira hauna kumhanya 100%.Nekuda kwenjodzi dzinongoitika dzoga, marongero emunharaunda uye zvimwe zvinhu, zvinobuda zvinofanirwa kuve zvishoma pane kugona kugadzira.Nekuda kwemutengo wakakwira wekugadzira wePVC muEurope neJapan, kugadzirwa kwePVC kwepasi rose kunonyanya kutariswa kuNortheast Asia, iyo China ine hafu yepasi rose PVC yekugadzira.
Zvinoenderana nedata remhepo, muna 2020, China, United States neJapan inzvimbo dzakakosha dzePVC dzekugadzira munyika, dzine huwandu hwekugadzira hunoverengera 42%, 12% uye 4% zvichiteerana.Muna 2020, mabhizinesi matatu epamusoro muPVC yepasi rose yegore rekugadzira kugona aive Westlake, shintech neFPC.Muna 2020, iyo PVC yegore yekugadzira kugona yaive 3.44 miriyoni matani, 3.24 miriyoni matani uye 3.299 miriyoni matani zvichiteerana.Chechipiri, mabhizinesi ane hunyanzvi hwekugadzira matani anopfuura mamirioni maviri anosanganisira inovyn.Kukwana kweChina kwese kwekugadzira mamwe matani mamiriyoni makumi maviri neshanu, ane goho remamiriyoni makumi maviri nerimwe ematoni muna 2020. Kune vanopfuura makumi manomwe vanogadzira PVC muChina, 80% avo vari calcium carbide nzira uye 20% inzira ye ethylene.
Mazhinji enzira yecalcium carbide yakanyura munzvimbo dzakapfuma muzviwanikwa zvemarasha seInner Mongolia neXinjiang.Nzvimbo yekudyara ye ethylene process inowanikwa munzvimbo dzemahombekombe nekuti iyo mbishi VCM kana ethylene inoda kutengwa kunze kwenyika.Kugadzirwa kweChina kunotora inenge hafu yenyika, uye nekuwedzera kunoramba kuchienderera mberi kweChina yekumusoro kwemaindasitiri cheni, iyo PVC yekugadzira nzira ye ethylene nzira icharamba ichiwedzera, uye China icharamba ichikanganisa chikamu chepasi rose chePVC.
