Polyether Polyols Production Technology

Polyether polyols are formed by ring opening polymerization of polyols, polyamines, or other active hydrogen containing compounds with oxidized olefins such as propylene oxide, ethylene oxide, and styrene oxide under the action of catalysts. Due to the varying properties and applications of products with different initiators and polymerization degrees, there are many varieties and grades of polyether products. Polyether polyols are mainly used in the polyurethane industry. Polyurethane materials have excellent properties, wide applications, and a variety of product types. According to the performance of polyether products, they can be divided into soft foam polyether, hard foam polyether, elastomeric polyether, polyether polyol (also known as graft polyether), and high resilience polyether.
