WHAKATOKANGA
Ko te Donfoam 812 te whakakotahi i nga polyol polyether e whakamahia ana mo te hanga pahuka i te paraka PUR.He pūtau rite te pahuka, he iti te kawe i te waiariki, he pai te mahi whakawera waiariki, he pai te mahi mura ahi, he iti te pāmahana kaore he kapiti whakaheke etc.
Ka whakamahia nuitia i roto i te mahi o nga momo mahi whakamaarama penei i te: hanga taiepa o waho, rokiroki makariri, taika, paipa nui etc.
