Terate® HT 5349 polyol is an aromatic polyester polyol of high functionality specifically engineered for use in polyurethane (PUR) closed-cell spray foams for both wall and roof insulation applications that require a fire-resistance rating. The recommended use level in such spray foam formulation is between 35 - 65% in the B-side polyol blends.
Terate® HT 5349 is designed to provide additional benefits specifically for closed-cell spray foam formulations.
Enhanced solubility with either HFC-245fa or HCFO-1233zd blowing agents
Formulation flexibility to achieve fire-resistance performance using a variety of B-side components
Insulation performance and compressive strength equivalent to industry leading closed-cell spray polyurethane foam systems.
