Terate® HT 5510

TERATE® HT 5510 polyol is an aromatic polyester polyol formulated for hydrocarbon blown PIR laminate systems; for use in flexible-faced board stock and metal-faced sandwich panels. It has a relatively high acid number and hydroxyl number. Aromaticity can help reduce smoke development substantially when the foam is burned, especially when used as a co-polyol in urethane systems.
