Terate® HT 5502

Terate® HT 5502 polyol is an aromatic polyester polyol specifically formulated for hydrocarbon blown PIR laminate systems requiring a higher acid number. Terate® HT 5502 polyols functionality and aromatic content enhance its flammability performance. When burned, polyisocyanurate and polyurethane foams containing Terate® HT 5502 polyol form char with minimal shrinkage and allow for high weight retention.
