For a long time the chemical hexabromocyclododecane, or HBCD, was the most economically significant flame retardant used in polystyrene foam for insulation materials. Our background paper, also available in English, provides answers to the most important questions concerning the phase-out.

Flame retardants reduce the flammability of objects and can therefore delay the onset of a fire. Some of the commonly used flame retardants, however, can be toxic to the environment and human health. They are widespread traceable in indoor spaces and nature.
