• Uses: Decabromodiphenyl ether is a brominated flame retardant that is used in conjunction with antimony trioxide in high impact polystyrene. DecaBDE is used as an additive flame retardant, and has a variety of applications including in plastics/polymers/composites, textiles, adhesives, sealants, coatings and inks. DecaBDE containing plastics are used in housings of computers and TVs, wires and cables, pipes and carpets. Adverse effects are reported for soil organisms, birds, fish, frog, rat, mice and humans.
