Polyether Polyols waxaa lagu sameeyaa ka falcelinta oksaydhka organic iyo glycol.

Oksaydhka dabiiciga ah ee ugu weyn ee laga faa'iidaysto waa Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.

Glycols-ka ugu muhiimsan ee la isticmaalo waa Ethylene Glycol, Propylene Glycol, Biyo, Glycerine, Sorbitol, Sucrose, THME.

Polyols waxay ka kooban yihiin kooxaha reactive hydroxyl (OH) kuwaas oo la falgala kooxaha isocyanate (NCO) ee isocyanates si ay u sameeyaan polyurethane.

Waxaa jira noocyo badan oo polyeter-ka ah oo loogu talagalay poliurethane.Qalabka PU ee leh waxqabadyo kala duwan ayaa lagu heli karaa falcelinta u dhaxaysa bilawga kala duwan iyo olefin polymerization.

Adiga oo wax ka beddelaya alaabta ceeriin ee PU ama beddelidda kicinta, waxqabadka polyeter-ka waa la beddeli karaa.Bilaabayaashan waxaa ka mid ah aalkolada diethyl, khamriga ternary, tetrahydrofuran, iyo polyeter polyeter aromatic, iwm.

ISTICMAALKA

Isticmaalka polyeter-ka loo isticmaalo PU wuxuu ka badan yahay 80%.Polyether polyurethane waa la kala saari karaa

Polyether Polyol (PPG),

Polymeric Polyol (POP),

Polytetramethylene ether glycol (PTMEG, oo sidoo kale loo yaqaan polytetrahydrofuran polyol) sida uu qabo bilawga.

Polyether polyols waxaa inta badan loo isticmaalaa xumbo adag PU, xumbo jilicsan, iyo alaabada xumbo-samaynta.
