Iinxalenye zesakhiwo sePolyurethane zisetyenziswa ngokubanzi kwizicelo zokunxiba ngenxa yokudityaniswa kwazo ezizodwa zeepropathi ezenza ukuba zilungele amashishini kunye neendawo ezahlukeneyo.Xa isetyenziswa njengezinto ezixhathisa ukunxiba.
Ingqayi yokuguba ephezulu ekwazi ukumelana nokunxitywa kwe-polyurethane inomsebenzi ogqwesileyo kushishino lwe-elektroniki kunye nezinto zebhetri.
