Isikhumba se-PVC (i-polyvinyl chloride) iwuhlobo lwangempela lwesikhumba esiyi-faux esakhiwa ngokufaka iqembu le-hydrogen esikhundleni seqembu le-chloride emaqenjini e-vinyl.Umphumela walokhu kushintshwa ube usuhlanganiswa namanye amakhemikhali ukuze kwakhiwe indwangu yepulasitiki eqinile futhi okulula ukuyinakekela.Lena incazelo ye-PVC Isikhumba.
I-PVC resin isetshenziswa njengempahla eluhlaza ukwenza isikhumba sokwenziwa se-PVC kuyilapho izindwangu ezingalukiwe ne-PU resin isetshenziswa njengempahla eluhlaza ukwenza isikhumba se-PU, eyaziwa nangokuthi isikhumba sokwenziwa.I-Polyvinyl chloride yayiwuhlobo lokuqala lwesikhumba esingumgunyathi esakhiwa ngawo-1920, futhi kwakuwuhlobo lwempahla ababeyidinga abakhiqizi baleyo minyaka ngoba yayinamandla futhi imelana kakhulu nezakhi zesimo sezulu kunezinto ababezisebenzisa ngaleso sikhathi.
