Most Toxic Forms of PBDE Discontinued

February 1, 2005

Great Lakes Chemical Corporation, the sole manufacturer of the two forms of polybrominated diphenyl ether (PBDE) flame retardants that are considered most toxic—penta-BDE and octa-BDE—ceased production of those chemicals at the end of 2004. The U.S. Environmental Protection Agency and Great Lakes Chemical announced the voluntary phaseout of these two chemicals in November 2003. The European Union and several U.S. states have also now banned the chemicals. Great Lakes is promoting its new Firemaster

® 550 as the replacement for the most widely used PBDE, penta-BDE, in flexible polyurethane foam. Firemaster 550 is a phosphorous-bromine flame retardant that is 27% bromine by weight. For information, visit www.greatlakes.com. More information on flame retardants can be found in
