    Production and use. TBBPA is produced by the reaction of bromine with bisphenol A. Most commercial TBBPA products consist of a mixture that differ in the degree of bromination with the formula C 15 H 16−x Br x O 2 where x = 1 to 4. Its fire-retarding properties correlate with %Br.The annual consumption in Europe has been estimated as 6.200

    Tetrabromobisphenol A

    Tetrabromobisphenol-A (TBBPA; Fig. 28.3), the highest volume flame retardant worldwide, is primarily (90%) a reactive BFR covalently bound to the polymer structure and less likely to be released into the environment than are additive flame retardants (Birnbaum and Bergman, 2010). It is used mainly for the production of circuit board polymers.

    Quality Concepts for the Improved Use of Recycled Polymeric

    Three BFRs families dominate the organic flame retardant market: tetrabromobisphenol A (TBBPA), polybrominated diphenyl ethers (PBDEs), and hexabromocyclododecane (HBCD). Flame retardants can be either reactive, when they are chemically bonded to the polymeric matrix, or additive, when they are added during processing.
