I-PVC yimpahla yeplastiki, egama layo elipheleleyo liyi-polyvinyl chloride. Iinzuzo zayo zixabiso eliphantsi, ubomi obude, ukubumba okulungileyo kunye nokusebenza okugqwesileyo. Iyakwazi ukumelana ne-corrosions kwiindawo ezahlukeneyo. Oku kuvumela ukuba isetyenziswe ngokubanzi kulwakhiwo, unyango, imoto, ucingo kunye nentambo kunye nezinye iindawo. Ekubeni eyona nto iphambili ekrwada ivela kwi-petroleum, iya kuba nefuthe elibi kokusingqongileyo. Iindleko zokusetyenzwa nokurisayikilishwa kwemathiriyeli ye-PVC ziphezulu kwaye kunzima ukuzirisayikilisha.
Izinto ze-PU sisishunqulelo semathiriyeli ye-polyurethane, eyinto yokwenziwa. Xa kuthelekiswa nezinto zePVC, izinto zePU zineenzuzo ezibalulekileyo. Okokuqala, izinto zePU zithambile kwaye zikhululekile. Kwakhona i-elastic engaphezulu, enokunyusa induduzo kunye nobomi benkonzo. Okwesibini, izinto zePU zinokuguda okuphezulu, ukungangeni kwamanzi, ubungqina beoyile kunye nokuqina. Kwaye akukho lula ukukrwempa, ukuqhekeka okanye ukonakala. Ukongeza, yinto ehambelana nokusingqongileyo kwaye ingaphinda isetyenziswe. Oku kunempembelelo enkulu yokukhusela kwindalo kunye ne-ikholoji. Izinto ze-PU zineenzuzo ezininzi kunezinto zePVC ngokwemiqathango yokuthuthuzela, ukungangeni kwamanzi, ukuqina kunye nobuhlobo bempilo yokusingqongileyo.
