Polyether Polyols yog tsim los ntawm reacting organic oxide thiab glycol.

Lub ntsiab organic oxide siv yog Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.

Lub ntsiab glycols siv yog Ethylene Glycol, Propylene Glycol, Dej, Glycerine, Sorbitol, Sucrose, THME.

Polyols muaj cov pab pawg reactive hydroxyl (OH) uas cuam tshuam nrog isocyanate (NCO) pawg ntawm isocyanates los ua polyurethanes.

Muaj ntau hom polyether polyols rau polyurethane.PU cov ntaub ntawv nrog kev ua tau zoo sib txawv tuaj yeem tau txais nrog cov tshuaj tiv thaiv ntawm cov pib sib txawv thiab olefin polymerization.

Los ntawm kev hloov kho PU cov ntaub ntawv raw lossis hloov cov catalyst, polyether kev ua tau zoo tuaj yeem hloov kho.Cov neeg pib no muaj xws li cawv cawv, ternary cawv, tetrahydrofuran, thiab aromatic polyether polyols, thiab lwm yam.

SIV

Kev siv ntawm polyether siv hauv PU yog ntau tshaj 80%.Polyether polyurethane tuaj yeem raug cais tawm

Polyether Polyol (PPG),

Polymeric Polyol (POP),

Polytetramethylene ether glycol (PTMEG, tseem hu ua polytetrahydrofuran polyol) raws li tus neeg pib.

Polyether polyols feem ntau yog siv hauv PU tawv ua npuas ncauj, mos ua npuas ncauj, thiab molding ua npuas ncauj khoom.
