Mtundu wa Molecular:nC3H6O

Mankhwala maselo kapangidwe:

Chemical Properties:

Ma polyether polyols ndi zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito popanga ma polyurethanes.

Ma polyurethanes opangidwa ndi polyether amawonetsa kukhazikika kwa hydrolytic komanso kukana kwambiri ma acid ofooka ndi maziko poyerekeza ndi ma polyester-based polyurethanes.

Polyether polyurethane akhoza kugawidwa mu zofewa thovu poliyetha, okhwima thovu poliyetha ndi elastomer ndi polyether malinga ndi ntchito mankhwala poliyesitala.

Komabe, ma polyether-based polyurethanes amatha kutengeka mosavuta ndi ma radiation a UV ndipo amapereka kukana kwamafuta ndi mafuta oyaka poyerekeza ndi polyester-based polyurethanes.

Ntchito:

Kugwiritsa ntchito polyether komwe kumagwiritsidwa ntchito mu PU ndikoposa 80%.Polyether polyurethane ikhoza kugawidwa m'magulu

Polyether Polyol(PPG),Polymeric Polyol (POP),Polytetramethylene ether glycol (PTMEG, yotchedwanso polytetrahydrofuran polyol) malinga ndi woyambitsa.

Ma polyether polyols amagwiritsidwa ntchito kwambiri mu thovu lolimba la PU, thovu lofewa, ndi zinthu zopangira thovu.
