OLELO HOOLAHA
ʻO DonFoam 824 / PIR kahi ʻano o ka hui ʻana i nā polyols e hoʻohana ana i ka hfc-245fa foaming agent, me ka polyol ma ke ʻano he kumu nui, i hui pū ʻia me kahi mea kōkua kūikawā, kūpono no ka insulation o ke kūkulu ʻana, ka lawe ʻana, ka pūpū a me nā huahana ʻē aʻe.Hoʻolālā kūikawā ʻia kēia mea no ka laina hoʻomau . ʻO ka huahana polyurethane i hoʻomākaukau ʻia ma ka hana ʻana me ka isocyanate nā mea maikaʻi aʻe:
--Ea-aloha, me ka luku ole i ka ozone papa
- Ka ikaika compressive kiʻekiʻe a me ka homogeneity maikaʻi o ka ikaika isotropic
-- Hana maikaʻi loa i ka hoʻokalakupua wela a me ke kūpaʻa dimensional
