Polyether vs Polyester Polyol

刘芳

Detailed comparison of polyether and polyester polyol synthesis methods, performance characteristics and applicable scenarios.

Polyether vs Polyester Polyol

Polyol is the base material for PU synthesis. Polyether and polyester types each have unique characteristics requiring balanced consideration of performance and cost.

Polyether Polyol

Made by ring-opening polymerization of propylene oxide or ethylene oxide, offering excellent hydrolysis resistance, low-temperature flexibility and lower viscosity for large-scale production.

Polyester Polyol

Made by condensation of dibasic acids and diols, superior mechanical strength and abrasion resistance but poorer hydrolysis resistance, used in high-performance elastomers and coatings.
