There are two major kind of polyols used in Polyurethane : polyester polyols and polyether polyols.
Polyester polyols are produced by reacting acid and glycol.
Main acids utilized are Adipic, Isophtalic, Terephtalic, Succinic, Sebacic
Main glycols utilized are MEG, DEG, BDO, HDO, NPG, TMP.
Polyether polyols are made by reacting organic oxide and glycol
Main organic oxide utilized are EO, PO, BO, Epichlorohydrin.
Main glycols utilized are EG, PG, Water, Glycerine, Sorbitol, Sucrose, THME.
The decision to use a polyether rather than polyester will depend on the final properties of the material (abrasion resistance, heat resistance, hardness, solvent resistance, shock absorption, …).
