Isikhumba se-PU nesikhumba se-PVC zombili izinto zokwenziwa ezivame ukusetshenziswa njengezinye zesikhumba sendabuko. Nakuba zifana ngokubukeka, zinomehluko othile ophawulekayo mayelana nokwakheka, ukusebenza, kanye nomthelela wendawo.
Isikhumba se-PU senziwe ngongqimba lwe-polyurethane oluhlanganiswe nezinto ezisekelayo. Ithambile futhi ivumelana nezimo kunesikhumba se-PVC, futhi inokwakheka kwemvelo okufana nesikhumba sangempela. Isikhumba se-PU futhi siphefumula kakhulu kunesikhumba se-PVC, okwenza kube lula ukusigqoka isikhathi eside. Ukwengeza, isikhumba se-PU sihambisana kahle nemvelo uma siqhathaniswa nesikhumba se-PVC njengoba singaqukethe amakhemikhali ayingozi njengama-phthalates futhi siyabola.
Ngakolunye uhlangothi, isikhumba se-PVC senziwe ngokumboza i-polymer yepulasitiki phezu kwezinto ezisekela indwangu. Ihlala isikhathi eside futhi imelana nokuhuzuka kunesikhumba se-PU, okuyenza ibe into efanelekile yokwenza izinto ezingaphansi kokuphathwa kabi, njengezikhwama. Isikhumba se-PVC sibuye singabizi futhi kulula ukusihlanza, okwenza kube ukukhetha okudumile kwezicelo ze-upholstery. Kodwa-ke, isikhumba se-PVC asiphefumuleki njengesikhumba se-PU futhi sinokuthungwa okuncane kwemvelo okungenzeka kungalingisi isikhumba sangempela eduze.
Kafushane, ngenkathi isikhumba se-PU sithambile, siphefumula kakhulu, futhi sihambisana 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 endaweni ezungezile.
