Iipolyether Polyols zenziwe ngokusabela kwi-organic oxide kunye ne-glycol.

Eyona oxide ye-organic esetyenziswayo yi-Ethylene oxide, iPropylene oxide, iButylene oxide, iEpichlorohydrin.

Iiglycols eziphambili ezisetyenziswayo yi-Ethylene Glycol, Propylene Glycol, Amanzi, Glycerine, Sorbitol, Sucrose, THME.

IiPolyols ziqulathe amaqela asebenzayo ehydroxyl (OH) athi asebenze kunye namaqela e-isocyanate (NCO) kwi-isocyanates ukwenza iipolyurethanes.

Kukho iintlobo ezininzi zeepolyether ze-polyurethane.Izinto ze-PU ezinomsebenzi ohlukeneyo zinokufunyanwa ngokusabela phakathi kwabaqalisi abahlukeneyo kunye ne-olefin polymerization.

Ngokuguqula izinto eziluhlaza ze-PU okanye ukutshintsha i-catalyst, ukusebenza kwe-polyether kunokuguqulwa.Aba baqalisi babandakanya i-diethyl alcohol, i-ternary alcohol, i-tetrahydrofuran, kunye ne-aromatics polyether polyols, njl.

USEBENZISA

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.
