Isikhumba se-PU kunye ne-PVC yesikhumba zizibini izinto zokwenziwa ezisetyenziswa njengeendlela ezizezinye zesikhumba. Ngelixa zifana nembonakalo, zinemibono engabonakaliyo ngokwemigaqo yokuqulunqwa, ukusebenza kunye nefuthe lokusingqongileyo.
Isikhumba sePu senziwe kwi-polyurethane ebotshwe kwizinto ezixhasayo. Ithambile kwaye iguquguquka ngakumbi kunesikhumba se-PVC, kwaye inomyalezo wendalo ofana nesikhumba sokwenene. Isikhumba se-PU sinokuphefumla ngakumbi kunesikhumba se-PVC, senza ukuba sikhululeke ukuba sinxibe ixesha elide. Ukongeza, isikhumba se-Pu sinobuhlobo obufanelekileyo ngokusingqongileyo xa kuthelekiswa nesikhumba se-PVC kuba ayinazo iikhemikhali eziyingozi ezinjengePthalates kwaye i-biodegraded.
Kwelinye icala, isikhumba se-PVC senziwa ngokudibana kweplasitiki kwi-polymer yeplastiki kwizinto ezixhasayo. Ihlala ixesha elide kwaye ixhathise ukuxhaphaza kunesikhumba se-punu, esenza ukuba ibe yinto efanelekileyo yokwenza izinto eziphantsi kokuphathwa gadalala, ezinjengeengxowa. Isikhumba se-PVC sikwaxabisa kwaye sinokucoca, sisenza ukhetho oludumileyo lwezicelo ze-upholstery. Nangona kunjalo, ulusu lwe-PVC aluphefumli njengolusi wesikhumba lwe-pu kwaye lunendawo encinci yendalo engasothunge ulusu lokwenyani ngokusondeleyo.
Isishwankathelo, ngelixa isikhumba se-PU sithambile, siphefumle ngakumbi, kunye nobuhlobo obunobuhlobo obunobuhlobo, kunye nokusingqongileyo okusingqongileyo, kwaye kulula kakhulu kwaye kube lula ukucoca. Xa uthatha isigqibo phakathi kwezinto ezimbini, kubalulekile ukuqwalasela ukusetyenziswa kwemali kunye neemfuno zomsebenzi wemveliso yokugqibela, kunye nefuthe elinokubakho kwindalo esingqongileyo.
