FR-522

FR-522, is a reactive, dibromoneopentyl glycol, flame retardant, containing 60% aliphatic bromine. Thermosetting polyester resins formulated with FR-522 have high chemical and flame resistance, minimal thermal discoloration and excellent light stability.

The high bromine content of FR-522 and its ready reaction into polyurethanes make it suitable for use in rigid polyurethane foams.
