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.

The initiator, type of olefin oxide and molecular weight mainly determine the physicochemical properties of polyether polyols: 1. The amount of reactive hydrogen of the initiator determines the functionality of the polyether. The reactivity of polyethers synthesized by different starting agents vari Read More
