Polyether Polyols

Polyether polyols are oligomers featuring ether linkages in the backbone and multiple terminal hydroxyl groups, primarily produced through the addition polymerization of an initiator and an epoxide. They are core raw materials in the polyurethane industry and are widely used in applications such as foams, coatings, and adhesives.
