Octabromodiphenyl ethers

Octabromodiphenyl ethers are organobromine compounds, as well as polybrominated diphenyl ethers containing four bromine atoms. Polybrominated diphenyl ethers (PBDEs) are flame-retardant man-made chemicals found in plastics used in a variety of consumer products to make them difficult to burn. PBDEs exist as mixtures of similar chemicals called congeners. Because they are mixed into plastics and foams rather than bound to them, PBDEs can leave the products that contain them and enter the environment. Octabromodiphenyl ethers are used in conjunction with antimony trioxide as a flame retardant in the housings of electrical and electronic equipment, mainly in the plastic acrylonitrile butadiene styrene, but also in high impact polystyrene, polybutylene terephthalate and polyamides.
