A na-eme polyether polyols site na mmeghachi omume organic oxide na glycol.

Isi organic oxide etinyere bụ Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.

Isi glycols eji eme ihe bụ Ethylene Glycol, Propylene Glycol, Water, Glycerine, Sorbitol, Sucrose, THME.

Polyols nwere otu reactive hydroxyl (OH) nke na-emeghachi omume na otu isocyanate (NCO) na isocyanates iji mepụta polyurethane.

Enwere ọtụtụ polyether polyols maka polyurethane.Enwere ike nweta ihe PU nwere arụmọrụ dị iche iche site na mmeghachi omume n'etiti ndị mmalite dị iche iche na olefin polymerization.

Site n'ịgbanwe ngwa ngwa PU ma ọ bụ ịgbanwe ihe na-akpali akpali, enwere ike gbanwee arụmọrụ polyether.Ndị mbido a gụnyere mmanya diethyl, mmanya ternary, tetrahydrofuran, na aromatic polyether polyols, wdg.
