inoa mea kūʻai：polyether polyol

ʻAno molekala:nC3H6O

Huahana molecular structure：

Na Waiwai Kemika:

ʻO nā polyether polyols nā mea nui i hoʻohana ʻia i ka hana ʻana i nā polyurethanes.

Hōʻike nā polyurethanes i hoʻokumu ʻia i ka polyether i hoʻonui ʻia i ke kūpaʻa hydrolytic a me ke kūpaʻa maikaʻi loa i nā ʻakika nāwaliwali a me nā kumu i hoʻohālikelike ʻia me nā polyurethanes-based polyester.

Hiki ke hoʻokaʻawale ʻia ka polyether polyurethane i ka polyether foam palupalu, polyether foam rigid a me ka elastomer me ka polyether e like me ka hana o nā huahana polyether.

Eia nō naʻe, ʻoi aku ka maʻalahi o nā polyurethanes e pili ana i ka polyether i ka radiation UV a hāʻawi i ke kūʻē maikaʻi ʻole i nā ʻaila a me nā wahie i hoʻohālikelike ʻia me nā polyurethanes-based polyester.

ʻO ka hoʻohana ʻana i ka polyether i hoʻohana ʻia ma PU ma mua o 80%.Hiki ke hoʻokaʻawale ʻia ka polyether polyurethane

Polyether Polyol(PPG),Polymeric Polyol (POP),ʻO Polytetramethylene ether glycol (PTMEG, i kapa ʻia ʻo polytetrahydrofuran polyol) e like me ka mea hoʻomaka.

Hoʻohana nui ʻia nā polyether polyols i loko o ka PU rigid foam, ka ʻūhā palupalu, a me ka hoʻoheheʻe ʻana i nā huahana.
