izina RY'IGICURUZWA：Yamazaki

Imiterere ya molekulari ：nC3H6O

Imiterere yibicuruzwa：

Ibikoresho bya Shimi:

Polyol polyoly nibintu byingenzi bikoreshwa mugukora polyurethanes.

Polyurethanes ishingiye kuri polyether yerekana imbaraga za hydrolytike kandi ikarwanya aside irike hamwe na base ugereranije na polyurethanes ishingiye kuri polyester.

Polyurethane irashobora kugabanywamo ibice byoroshye byoroshye, ifuro rinini cyane hamwe na elastomer hamwe na polyether ukurikije imikorere yibicuruzwa byinshi.

Nyamara, polyurethanes ishingiye kuri polyether irashobora kwibasirwa cyane nimirasire ya UV kandi itanga imbaraga nke zamavuta na lisansi ugereranije na polyurethanes ishingiye kuri polyester.

Gusaba:

Imikoreshereze ya polyether ikoreshwa muri PU irenga 80%.Polyetherthane irashobora gushyirwa mubikorwa

Kumurongo(PPG),Polymeric Polyol (POP),Polytetramethylene ether glycol (PTMEG, nanone yitwa polytetrahydrofuran polyol) nkuko byatangijwe na nyirubwite.

Polyol polyoly ikoreshwa cyane cyane muri PU igoye cyane, ifuro yoroshye, hamwe nibicuruzwa bibumba.
