Khoom npe:polyether polyol

Molecular hom:nco 3h6o

Cov khoom siv molecular:

Chemical Properties:

Polyether polyols yog cov khoom siv tseem ceeb hauv kev tsim cov polyurethanes.

Polyether-raws li polyurethanes nthuav tawm txhim kho hydrolytic stability thiab zoo heev tiv taus rau cov acids tsis muaj zog thiab cov hauv paus piv rau polyester-based polyurethanes.

Polyether polyurethane tuaj yeem muab faib ua npuas ncauj polyether, nruj ua npuas ncauj polyether thiab elastomer nrog polyether raws li kev ua tau zoo ntawm cov khoom siv polyether.

Txawm li cas los xij, polyether-based polyurethanes muaj qhov cuam tshuam rau UV hluav taws xob ntau dua thiab muab cov roj tsis zoo rau cov roj thiab roj piv rau polyester-based polyurethanes.

Daim ntawv thov:

Kev siv ntawm polyether siv hauv PU yog ntau tshaj 80%.Polyether polyurethane tuaj yeem raug cais tawm

Polyether Polyol(PPG),Polymeric Polyol (POP),Polytetramethylene ether glycol (PTMEG, tseem hu ua polytetrahydrofuran polyol) raws li tus neeg pib.

Polyether polyols feem ntau yog siv hauv PU tawv ua npuas ncauj, mos ua npuas ncauj, thiab molding ua npuas ncauj khoom.
