Isikhumba se-PU nesikhumba se-PVC zombili izinto zokwenziwa ezivame ukusetshenziswa njengezinye izindlela zesikhumba sendabuko. Ngenkathi zifana ngokubukeka, zinomehluko othile ophawuleka ngokwemigomo yokwakheka, ukusebenza, kanye nomthelela wezemvelo.
Isikhumba se-PU senziwa ngongqimba lwe-polyurethane oluboshelwe ezintweni ezifuywayo. Kuthambile futhi kuvumelana nezimo kunesikhumba se-PVC, futhi kunokwehla okungokwemvelo okufana nesikhumba sangempela. Isikhumba se-PU futhi siphefumula ngokwedlulele ukwedlula isikhumba se-PVC, okwenza kube ntofontofo ukugqoka isikhathi eside. Ngaphezu kwalokho, ngesikhumba se-pu sinobungani bemvelo ngokuqhathaniswa nesikhumba se-PVC selokhu kuqukethe amakhemikhali ayingozi afana nama-phthalates futhi angathandeki.
Ngakolunye uhlangothi, isikhumba se-PVC senziwa ngokuhlanganisa i-polymer epulasitiki ezintweni zokusekela zendwangu. Ihlala isikhathi eside futhi imelana ne-abrasion kunesikhumba se-pu, okwenza kube yinto efanelekile yokwenza izinto ezingaphansi kokuphathwa kabi, njengezikhwama. Isikhumba se-PVC futhi asibizi futhi kulula ukusihlanza, okwenza kube ukukhetha okuthandwayo kwezicelo ze-UPholstery. Kodwa-ke, isikhumba se-PVC asiphefumuli njengesikhumba se-pu futhi sinokuthungwa okuncane kwemvelo okungenzeka kungalingisa isikhumba sangempela eduze.
Ngamafuphi, kuyilapho isikhumba se-pu sithambile, siphefumula ngokwengeziwe, futhi ngokwemvelo esinemvelo, isikhumba se-PVC sihlala isikhathi eside futhi kulula ukusihlanza. Lapho unquma phakathi kwezinto zokwakha ezimbili, kubalulekile ukucubungula ukusetshenziswa okuhlosiwe kanye nezidingo zokusebenza komkhiqizo wokugcina, kanye nomthelela ongaba khona emvelweni.
