Description

Hexabromocyclododecane (HBCD) is a white odorless nonvolatile solid compound which is used as an additive flame retardant on its own, or in combination with other flame retardants. It is used as a flame retardant mainly in building insulation composed of extruded or expanded polystyrene foam. A minor use is in flame retardant back-coats of some upholstery textiles.

Hexabromocyclododecane Use and Manufacturing

The commercially available brominated flame retardant hexabromocyclododecane (HBCD) is lipophilic, has a high affinity to particulate matter and low water solubility. It is used as a flame retardant additive, with the intent of delaying ignition and slowing subsequent fire growth during the service life of vehicles, buildings or articles, as well as while materials are stored. The main uses of HBCD are in flame-retarded expanded (EPS) and extruded (XPS) polystyrene foam insulation, with smaller scale use in textile applications and electric and electronic appliances (high impact polystyrene/HIPS). In textiles HBCD is used in back-coatings for upholstery and other interior textiles, including automotive applications.
