OLELO HOOLAHA
ʻO Donfoam 812 hoʻohui i nā polyether polyols i hoʻohana ʻia no ka hana ʻana i ka huʻu poloka PUR.Loaʻa i ka pahu kaʻa like pū, haʻahaʻa thermal conductivity, thermal insulation hana maikaʻi, flame retardant hana maikaʻi, haʻahaʻa haʻahaʻa haʻahaʻa ʻaʻohe shrinking māwae etc.
Hoʻohana nui ʻia i ke kaʻina hana o nā ʻano hana insulation e like me: ke kūkulu ʻana i ka pā o waho, ka mālama anuanu, nā pahu, nā paipu nui etc.
