Description
2,2-Bis (bromomethyl) -1,3-propanediol is a reactive flame retardant containing 60% fatty bromine. It is used in a variety of thermosetting polyesters and can provide a wider choice of ester properties than acid anhydride flame retardants. Resins formulated with 2,2-Bis (bromomethyl) -1,3-propanediol have high flame retardancy, minimal thermal discoloration, and good light stability. 2,2-Bis (bromomethyl) -1,3-propanediol has a high bromine content and is easily combined with polyurethane. It is especially suitable for rigid polyurethane foam. 2,2-Bis (bromomethyl) -1,3-propanediol is more and more widely used in free-CFC foam systems to improve its flame retardancy.
