Polyether polyols are polymerized products produced by the catalyzed addition of monomers like propylene oxide (PO) and/or ethylene oxide (EO) to an initiator/starter. Typical starters are glycerin, mono-propylene glycol, sucrose, sorbitol, water and amines.

Polyether polyols, when combined with di isocyanates, are used in urethane applications, such as flexible foam, and in Coatings, Adhesives, Sealants & Elastomer (CASE) systems. As a result, we may encounter them in a wide variety of goods including furniture, car seating, bedding, paints and coatings, artificial sports tracks, playground surfaces, ski suits and other waterproof leisure wear.

Polyols are not classified for physical hazards. They are not flammable, but will burn. They are not classified for health or environmental effects according to GHS criteria and can generally be considered as low hazard products.
