Iipropati zeMichiza:

Iipolyether polyols zizinto eziphambili ezisetyenziselwa ukuveliswa kwe-polyurethanes.

I-polyurethanes esekwe kwi-polyurethanes ibonisa uzinzo oluphuculweyo lwe-hydrolytic kunye nokuchasana okugqwesileyo kwiiasidi ezibuthathaka kunye neziseko xa kuthelekiswa ne-polyester-based polyurethanes.

I-polyether polyurethane inokohlulwa ibe yi-polyether yogwebu ethambileyo, i-polyether ye-foam eqinile kunye ne-elastomer ene-polyether ngokokusebenza kweemveliso ze-polyether.

Nangona kunjalo, i-polyether-based polyurethanes ichaphazeleka ngakumbi kwimitha ye-UV kwaye inika ukuxhathisa okulambathayo kwi-oyile kunye namafutha xa kuthelekiswa ne-polyester-based polyurethanes.

Isicelo:

Ukusetyenziswa kwe-polyether esetyenziswe kwi-PU kungaphezulu kwe-80%.I-polyether polyurethane ingahlelwa

Polyether Polyol(PPG),IPolymeric Polyol (POP),I-Polytetramethylene ether glycol (PTMEG, ebizwa ngokuba yi-polytetrahydrofuran polyol) ngokutsho komqalisi.

Iipolyether polyols zisetyenziswa ikakhulu kwi-PU igwebu eliqinileyo, ugwebu oluthambileyo, kunye neemveliso zogwebu lokubumba.
