It is a brominated flame retardant used in extruded (XPS) and expanded (EPS) polystyrene foam that is used as thermal insulation in the building industry. Hexabromocyclododecane is also a persistent organic pollutant, thus its use is controversial. Bromine is a halogen element with the symbol Br and atomic number 35. Diatomic bromine does not occur naturally, but bromine salts can be found in crustal rock. (L625, 1082)"}]
