Donpipe 322 HCFC-141B Huihuinga Poto mo te anga paipa
INtroduction
Ko Donpipe 322 te ahua o te haehaa whakaranu me te HCFC-141B hei kaihoko whakakakahu, ko te polyol hei rauemi matua, whakaranu ki tetahi awhina motuhake. Ko tenei rauemi e tika ana mo nga anga ngongo waiariki e whakamahia ana mo te wai, te hinu hinu me te hau .Ko te hua polyurethane i whakaritea ma te whakaohooho i a Isocyanate:
- Te kaha composive pai me te pumau
- Te utu o te pūtau kati me te pai o te mahi parewai
- He mahi whakahiato
