I-PVC iyipulasitiki evamile evame ukwenziwa ibe amapayipi nezinto zokufakelwa, amashidi namafilimu, njll.

Ishibhile futhi iyakwazi ukubekezelela ama-asidi athile, ama-alkali, usawoti, kanye nezinyibilikisi, okwenza ifaneleke kakhulu ukuthintana nezinto ezinamafutha. Ingenziwa ibonakale icacile noma ingabonakali njengoba kudingeka, futhi kulula ukuyipenda. Isetshenziswa kabanzi ekwakheni, ocingweni nasezintanjeni, ekupakisheni, ezimotweni, kwezokwelapha nakweminye imikhakha.

Kodwa-ke, i-PVC ayinakho ukuzinza kokushisa okuhle futhi ithambekele ekuboleni emazingeni okushisa okucubungula, ikhiphe i-hydrogen chloride (HCl), okuholela ekushintsheni kombala kwezinto kanye nokusebenza okunciphile. I-PVC emsulwa iyaphuka, ikakhulukazi ithambekele ekuqhekekeni emazingeni okushisa aphansi, futhi idinga ukungezwa kwama-plasticizer ukuze kuthuthukiswe ukuguquguquka. Inokumelana nesimo sezulu okubi, futhi uma ivezwa ekukhanyeni nasekushiseni isikhathi eside, i-PVC ithambekele ekugugeni, ekushintsheni kombala, ekuqhekekeni, njll.

Ngakho-ke, iziqinisi ze-PVC kumele zengezwe ngesikhathi sokucubungula ukuze kuvinjelwe ngempumelelo ukubola kokushisa, kwandise isikhathi sokuphila, kugcinwe ukubukeka, futhi kuthuthukiswe ukusebenza kokucubungula.

Ukuze kuthuthukiswe ukusebenza nokubukeka komkhiqizo oqediwe, abakhiqizi bavame ukwengeza inani elincane lezithasiselo.I-OBAkungathuthukisa ubumhlophe bemikhiqizo ye-PVC. Uma kuqhathaniswa nezinye izindlela zokwenza mhlophe, ukusebenzisa i-OBA kunezindleko eziphansi nemiphumela ebalulekile, okwenza ifaneleke ekukhiqizweni okukhulu.Ama-Antioxidant, iziqinisi zokukhanya,Izifutho ze-UV, ama-plasticizer, njll. kuyizinketho ezinhle zokwandisa isikhathi sokuphila komkhiqizo.
