Isikhumba se-PU kanye nesikhumba se-PVC zombili ziyizinto zokwenziwa ezivame ukusetshenziswa njengezinye izindlela esikhundleni sesikhumba sendabuko. Nakuba zifana ngokubukeka, zinomehluko ophawulekayo mayelana nokwakheka, ukusebenza, kanye nomthelela emvelweni.
Isikhumba se-PU senziwe ngesendlalelo se-polyurethane esiboshwe entweni engemuva. Sithambile futhi siguquguquka kakhulu kunesikhumba se-PVC, futhi sinokwakheka kwemvelo okufana nesikhumba sangempela. Isikhumba se-PU siphefumula kangcono kunesikhumba se-PVC, okwenza kube lula ukusigqoka isikhathi eside. Ngaphezu kwalokho, isikhumba se-PU sinobungani nemvelo uma siqhathaniswa nesikhumba se-PVC njengoba singenawo amakhemikhali ayingozi njenge-phthalates futhi siyabola.
Ngakolunye uhlangothi, isikhumba se-PVC senziwa ngokumboza i-polymer yepulasitiki phezu kwendwangu engemuva kwendwangu. Sihlala isikhathi eside futhi simelana nokuguguleka kunesikhumba se-PU, okwenza sibe yinto efanelekile yokwenza izinto eziphathwa kabi, njengezikhwama. Isikhumba se-PVC sibuye singabizi kakhulu futhi kulula ukusihlanza, okwenza kube ukukhetha okuthandwayo kokusetshenziswa kwe-upholstery. Kodwa-ke, isikhumba se-PVC asiphefumuli njengesikhumba se-PU futhi sinokwakheka okungokwemvelo okungahle kungafani nesikhumba sangempela eduze.
Ngamafuphi, yize isikhumba se-PU sithambile, siphefumula kalula, futhi sinobungani nemvelo, isikhumba se-PVC sihlala isikhathi eside futhi kulula ukusihlanza. Lapho unquma phakathi kwezinto ezimbili, kubalulekile ukucabangela ukusetshenziswa okuhlosiwe kanye nezidingo zokusebenza komkhiqizo wokugcina, kanye nomthelela ongaba khona emvelweni.
