Polyether kūikawā – polyether PET polyether kaumaha molekala
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, kokoke nā mea mechanical o ka elastomer i nā PTMG.
Hoʻohana nui ʻia i loko o nā ʻano hoʻohālikelike paʻa, me nā ʻano mechanical haʻahaʻa haʻahaʻa maikaʻi loa a me kahi ākea o nā mahana hana.
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.
