Polyether polyols for polyurethanes : Multranol®

Polyurethanes enhance our lives every day. Polyurethane (PU) foams improve the energy efficiency of homes. PU coatings protect cars and give them a unique appearance. PU sealants and liquid membranes prevent water from penetrating the roof of many commercial buildings.

Many different types of polyols and polyisocyanates – the building blocks of polyurethanes – are used to impart diverse, high-performance properties.

Multranol® polyether polyols from Covestro are low-viscosity ingredients that yield polyurethanes with good resistance to hydrolysis.

Our Multranol® polyether polyols are used in the production of adhesives and sealants, flexible and rigid foams, and reaction injection-molded (RIM) urethanes. In some cases, they are the major reactant, while in others they function as a modifier.

Chemistries used to prepare Multranol® polyols include :

•     Ethylene oxide/ propylene oxide
•     Sucrose
•     Amines
•     Sucrose-amines
•     Soybean oil and glycerin (renewable)

Various grades of Multranol® polyols have been developed in response to the needs of formulators. We are continually building on our extensive expertise in polyurethane technology, creating new polyether polyols for advanced polyurethane applications.
