Terate® HT 5350 polyol is a highly versatile aromatic polyester polyol recommended for use in polyurethane (PUR) applications that require low viscosity, enhanced blowing agent compatibility, and a fire-resistance rating. For closed-cell spray foams for wall insulation applications, the recommended use level is between 35 - 65% in the B-side polyol blends.
