Decabromodiphenyl ether

Decabromodiphenyl ether (also known as decaBDE, deca-BDE, DBDE, deca, decabromodiphenyl oxide, DBDPO, or bis(pentabromophenyl) ether) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs).

Composition, uses, and production

Commercial decaBDE is a technical mixture of different PBDE congeners, with PBDE congener number 209 (decabromodiphenyl ether) and nonabromodiphenyl ether being the most common. The term decaBDE alone refers to only decabromodiphenyl ether, the single "fully brominated" PBDE.

DecaBDE is a flame retardant. The chemical "is always used in conjunction with antimony trioxide" in polymers, mainly in "high impact polystyrene (HIPS) which is used in the television industry for cabinet backs." DecaBDE is also used for "polypropylene drapery and upholstery fabric" by means of backcoating and "may also be used in some synthetic carpets."

The annual demand worldwide was estimated as 56,100 tonnes in 2001, of which the Americas accounted for 24,500 tonnes, Asia 23,000 tonnes, and Europe 7,600 tonnes. In 2012 between 2500 and 5000 metric tonnes of Deca-BDE was sold in Europe. As of 2007, Albemarle in the U.S., Chemtura in the U.S., ICL-IP in Israel, and Tosoh Corporation in Japan are the main manufacturers of DecaBDE.
