TERATE® HT 5350 by Stepan Company is a highly versatile aromatic polyester polyol. It is suitable for use in polyurethane (PUR) applications that requires low viscosity, enhanced blowing agent compatibility, and a fire-resistance rating. It delivers burn performance in industry testing, forming char with minimum shrinkage and high weight retention. TERATE® HT 5350 improves ease of processing during rigid foam production and cold adhesion for spray applications. Recommended use level for closed-cell spray foams for wall insulation applications is 35-65% in the B-side polyol blends.
