Polyether polyols are versatile polymers essential in polyurethane production, synthesized by polymerizing ethylene oxide and propylene oxide onto multifunctional starters. This article explores various polyether polyol types, including polypropylene glycol, EO-terminated, PTHF, and high-functionality polyols, highlighting their chemical structures, properties, and applications in flexible and rigid foams, elastomers, and CASE products. The balance of hydrophilicity, reactivity, and molecular weight enables tailored polyurethane materials with excellent flexibility, durability, and chemical resistance, meeting diverse industrial needs.
Polyether polyols are essential building blocks in polyurethane production, offering excellent hydrolytic stability, flexibility, and chemical resistance. Synthesized through epoxide polymerization with multifunctional initiators, these polyols can be tailored for diverse applications including flexible and rigid foams, elastomers, and coatings. Their unique properties make them indispensable across industries such as automotive, construction, and furniture. Despite some limitations like UV sensitivity, ongoing innovations continue to expand their utility and sustainability.
The basic refining methods for polyether polyols can be broadly classified as follows: (1) Neutralization using inorganic or organic acids. In the polymerization reaction for the production of polyether polyol, inorganic acids are rarely used as neutralizing agents for systems using alkali metal hyd
The main raw materials for the production of polyether polyols are starting agents, epoxides, catalysts, catalyst removers or deactivators, and post-treatment agents. The starting agents are low molecular compounds containing hydroxyl groups and low molecular compounds containing amino groups or hyd
