Dibromoneopentyl Glycol is a reactive flame retardant; it contains 60% of aliphatic bromine and of high purity.
Dibromoneopentyl Glycol can be formulated over a wide range of compositions with thermosetting polyester resins to provide better performance than those available with anhydride flame retardant. Resins formulated with Dibromoneopentyl Glycol have high chemical and flame resistance, minimal thermal discoloration and excellent light stability. Its high bromine content facilitates its reaction into polyurethanes which makes it suitable for use in rigid polyurethane foams. It is increasingly used in CFC-free foam systems designed to meet more stringent standards of flame retardancy.
