Isikhumba se-PU kunye nesikhumba se-PVC zombini zizinto ezenziwe ngokwenziwa ezisetyenziswa rhoqo njengezinye iindlela endaweni yesikhumba sendabuko. Nangona zifana ngenkangeleko, zinomahluko ophawulekayo ngokwendlela ezibunjwe ngayo, ukusebenza kwazo, kunye nempembelelo yazo kwindalo esingqongileyo.
Isikhumba se-PU senziwe ngomaleko we-polyurethane odityaniswe nezinto ezingasemva. Sithambile kwaye siguquguquka ngakumbi kunesikhumba se-PVC, kwaye sinobume bendalo obufana nesikhumba sokwenyani. Isikhumba se-PU sikwaphefumla ngakumbi kunesikhumba se-PVC, okwenza kube lula ukunxiba ixesha elide. Ukongeza, isikhumba se-PU sinobuhlobo nokusingqongileyo xa sithelekiswa nesikhumba se-PVC kuba asinazo iikhemikhali eziyingozi ezifana ne-phthalates kwaye siyabola.
Kwelinye icala, ulusu lwePVC lwenziwa ngokugquma ipolymer yeplastiki kwimpahla engasemva ngelaphu. Luhlala ixesha elide kwaye alunakukukrala kunesikhumba sePU, nto leyo eyenza ukuba lube yinto efanelekileyo yokwenza izinto eziphathwa gadalala, njengeengxowa. Ulusu lwePVC lukwabiza kancinci kwaye kulula ukulucoca, nto leyo eyenza ukuba lube lolona khetho luthandwayo kwiimpahla zokufakelwa. Nangona kunjalo, ulusu lwePVC aluphefumli njengesikhumba sePU kwaye lunesimo esincinci sendalo esingenakufana nesikhumba sokwenyani.
Ngamafutshane, nangona ulusu lwe-PU luthambile, luphefumla lula, kwaye lunobuhlobo nokusingqongileyo, ulusu lwe-PVC luhlala ixesha elide kwaye kulula ukulucoca. Xa ukhetha phakathi kwezi zinto zimbini, kubalulekile ukuqwalasela iimfuno zokusetyenziswa kunye nokusebenza kwemveliso yokugqibela, kunye nefuthe elinokubakho kwindalo esingqongileyo.
