Terate® HT 5170 is a medium colored, aromatic polyester polyol with inherent functionality and fire performance advantages over polyether polyols. This product is designed to retain the advantages of Terate® 4020 and 2031 while offering higher hydroxyl value and functionality to allow for further substitution of polyether polyols in traditional polyurethane systems. Terate® HT 5170 also offers improved substrate adhesion, flowability and processing latitude. Polyurethane (PUR) spray formulations using Terate® HT 5170 typically produce foams that form char with minimal shrinkage and high weight retention in flammability testing while maintaining lighter in appearance foam color.
