Deca-bromodiphenyl ether

The term brominated flame retardant (BFR) incorporates more than 175 different types of substances, which form the largest class of flame retardants other classes are phosphorus-containing, nitrogen-containing, and inorganic flame retardants (Bimbaum and Sttaskal 2004). The major BFR substances in use today (depicted in Fig. 4.6) are tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD), and mixtures of polybrominated diphenyl ethers (PBDEs) (namely, deca-bromodiphenyl ether (DBDE), octabromodiphenyl ether (OBDE), and pentabro-modiphenyl ether (pentaBDE)). 

A further five chemicals (bisphenol A, deca-bromodiphenyl ether, medium-chained chlorinated paraffins, phthalates, trichloroethylene) were included due to information provided by regulators during interviews or available in referenced literature...

Mass Spectrum The ability of the present methods to identify PBDEs and deca-bromodiphenyl ether (decaBDE) in the plastic samples that contain several BFRs. 

Decabromodiphenyl oxide - bro-(i)mo-(i) di- fe-n l ak- Sld (deca-bromodiphenyl either) n. Diphenyl ether in, which all ten phenyl hydrogens have been replaced by bromine, containing 83% bromine. The commercial product, a free-flowing white powder, is much used as a flame retardant in high-impact polystyrene and structural foam, usually with synergistic antimony oxide. Typical would be 12% decabromodiphenyl oxide and 4% antimony oxide in the resin See image). 

California has also decided not to ban the deca compound. Its legislation eliminating the use of penta- and octa-bromodiphenyl ether will take effect on January 1, 2008. The ban is not expected to have a major effect on the market when it comes into force. Other American states have different policies. In New York State, it is forbidden under A9207 (April 1, 2004) to manufacture products containing more than one-tenth of one per cent of penta, octa or deca BDE. Washington State has also moved against all three compounds.
