Different types of BFRs

Among the many brominated flame retardants (BFRs) used in the world the main commercial BFRs are the following:

• TBBPA: Tetrabromobisphenol –A
• HBCD: Hexabromocyclododecane
• Deca-BDE (Decabromodiphenyl ether)

Other brominated polymers such as brominated epoxy, brominated polystyrene, brominated polycarbonate, poly (brominated acrylate), and brominated polyols are also used. Some brominated polymers have been phased out in certain regions:

• Octa-BDE (Octabromodiphenyl ether) - Phased out in Europe
• Penta-BDE (Pentabromodiphenyl ether) - Phased out in Europe
• PBB: Polybrominated biphenyls - Phased out in Europe

Each of these Brominated Flame Retardants have very different properties.
