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.
