Uses

DecaBDE is used in conjunction with antimony trioxide as a flame retardant in rigid plastics used in making cars and consumer goods such as electronic appliances. Other uses are the backcoating of upholstery furniture and construction materials.^[1] The annual consumption worldwide was estimated as 56,100 tons in 2001, of which 7,600 tons were used by the European industry.^[2] The manufacture of the chemical is no longer taking place in Europe. Antimony trioxide is the most important commercial compound of antimony. ...
