Polyether Kūikawā-Low Molecular Weight PET Polyether
Nā waiwai a me nā mea hoʻohana
He wai ia ma ka lumi wela, kahi kūpono e hoʻohana a hana. ʻO ka mahana hoʻololi aniani o -80 ℃, me ka hana haʻahaʻa haʻahaʻa maikaʻi loa, nā waiwai mechanical o kāna mau huahana elastomer a me PTMG kokoke i ka PTMG, hiki ke hoʻololi i ka PTMG i loko o ke kaiapuni haʻahaʻa haʻahaʻa.
Me ka hoʻololi molekala maikaʻi, hiki iā ia ke hoʻololi i ka PTMG i ka ʻili kūlohelohe a me ka inika paʻi; hiki ke hoʻohanaʻia i nā mea hoʻopili haʻahaʻa haʻahaʻa, nā uhi, polyurethane elastomers a pēlā aku.
