Virgin High-Function Ester (Ester) Polyol
SChemTech's virgin ester polyol series (ES-65 to ES-305) is built for demanding PU applications.
Product Overview
SChemTech's virgin ester polyol series (ES-65 to ES-305) is built for the most demanding PU applications. Ester-bond chemistry delivers dimensional stability, flame retardancy, and high-temperature resistance that recycled grades alone cannot match — making it the right choice for rigid insulation, UPR, and FR systems where specifications cannot move.
