ʻO Phthalic Anhydride Polyester polyol
ʻO kēia pūʻulu o nā polyols he mau polyol polyester aromatic i hoʻomākaukau ʻia e ka polycondensation a i ʻole ka hoʻololi ʻana o ka phthalic anhydride, diethylene glycol a me nā mea maka.Hoʻohana nui ʻia lākou ma ke kahua o ka ʻūhā paʻakikī a me nā mea hoʻopili.Loaʻa iā lākou nā pōmaikaʻi o ka haʻahaʻa haʻahaʻa, haʻahaʻa kala, kiʻekiʻe ka hopena hopena, maikaʻi hydrolysis paʻa, kiʻekiʻe aromatic maʻiʻo, maikaʻi paʻa a me ka fluidity o composite mea, A hiki ke hoʻololi i ka huahana e like me nā koi o ka mea kūʻai aku.
Hiki ke hoʻohana nui ʻia kēia moʻo polyester polyols i loko o ka friji, mālama anuanu, hoʻopuʻi, ikehu lā, pipelines thermal, insulation hale a me nā wahi ʻē aʻe o ka haku mele paʻakikī, kekahi o nā huahana adhesive.
