ʻO Donfoam 812PIR HCFC-141B kumu hoʻohui i nā polyols no ka pahu pahu PIR
OLELO HOOLAHA
ʻO DonFoam 812 / PIR kahi ʻano o ka hui ʻana i nā polyols me ka hcfc-141b foaming agent, me ka polyol ma ke ʻano he kumu nui, i hui pū ʻia me ka mea kōkua kūikawā, kūpono no ka insulation o ke kūkulu ʻana, ka lawe ʻana, ka pūpū a me nā huahana ʻē aʻe. ʻO ka huahana polyurethane i hoʻomākaukau ʻia e ʻO ka pane ʻana me ka isocyanate he mau mea maikaʻi kēia:
1.Foam loaʻa ka ikaika like ʻole a me ke kūpaʻa dimensional ma nā ʻaoʻao āpau
2. Hiki keʻokiʻokiʻia nā huahana foam i nāʻano likeʻole e like me nā koi o ka huahana
3.Excellent thermal insulation hana
