He rauemi hangai te hiako PU me te hiako PVC e whakamahia whānuitia ana hei whakakapi i te hiako tuku iho. Ahakoa he rite te āhua, he rerekētanga nui kei a rāua i roto i te hanganga, te mahi, me te pānga ki te taiao.
He mea hanga te hiako PU mai i tētahi paparanga polyurethane e herea ana ki tētahi rauemi tautoko. He ngawari ake, he ngāwari ake i te hiako PVC, ā, he āhua tūturu ake tōna e rite ana ki te hiako tūturu. He pai ake te manawa o te hiako PU i te hiako PVC, ā, he pai ake te mau mō te wā roa. Hei tāpiri, he pai ake te taiao o te hiako PU ki te hiako PVC nā te mea kāore he matū kino pēnei i te phthalates, ā, he pirau hoki.
I tētahi atu taha, ka hangaia te hiako PVC mā te paninga i tētahi polymer kirihou ki runga i tētahi rauemi papanga. He pakari ake, he ātete hoki ki te pakaru i te hiako PU, he mea pai mō te hanga i ngā taonga ka taea te whakahaere uaua, pērā i ngā putea. He iti te utu o te hiako PVC, ā, he ngāwari ki te horoi, he mea rongonui mō ngā tono whakapaipai. Heoi, kāore te hiako PVC e rite te manawa ki te hiako PU, ā, he iti ake te kakano tūturu, kāore pea e rite ki te hiako tūturu.
Hei whakarāpopototanga, ahakoa he ngawari ake te hiako PU, he ngāwari ake te manawa, he pai ake hoki mō te taiao, he pakari ake te hiako PVC, ā, he ngāwari ake te horoi. I te wā e whiriwhiri ana i waenga i ngā rauemi e rua, he mea nui kia whakaarohia te whakamahinga me ngā whakaritenga mahi o te hua whakamutunga, tae atu ki te pānga pea ki te taiao.
