Application
Tetrabromophthalic Anhydride(TBPA) is used in polyester, unsaturated polyester, epoxy resin, as a reactive flame-retardant; used in polystyrene, polypropylene, polyethylene and ABS resin, as an additive flame retardant; used in various engineering plastics to resist burning based on its excellent thermal stability. It is a highly efficient reactive aromatic bromine source. In some cases derivatives can be substituted for higher bromine-containing flame retardants, allowed for the highest level of bromine to be reacted into unsaturated polyesters at comparable monomer levels.
