Polyether Kūikawā-Kaumaha Molekala Haʻahaʻa PET Polyether
Nā Waiwai a me nā Hoʻohana
He wai ia i ka mahana o ka lumi, kahi mea maʻalahi e hoʻohana a hana. ʻO ka mahana hoʻololi aniani o -80 ℃, me ka hana haʻahaʻa maikaʻi loa, nā waiwai mechanical o kāna huahana elastomer a me PTMG kokoke i ka PTMG, hiki ke pani i ka PTMG i ke kaiapuni haʻahaʻa haʻahaʻa.
Me ka maʻalahi o ka molekala maikaʻi, hiki iā ia ke pani i ka PTMG i ka ʻili hana maʻalahi a me ka ʻīnika paʻi; hiki ke hoʻohana ʻia i nā mea hoʻopili haʻahaʻa haʻahaʻa, nā uhi, nā elastomers polyurethane a pēlā aku.
