In 2008, hexabromocyclododecane (HBCD) was proposed for listing under Annex A to the Stockholm Convention and the substance is currently under review by the Convention’s Persistent Organic Pollutants Review Committee. At present, the main uses of HBCD are in the polymer and textile industries. HBCD is used in four principal product types, which are Expandable Polystyrene (EPS), Extruded Polystyrene (XPS), High Impact Polystyrene (HIPS) and in polymer dispersions for textiles. Due to the increasing awareness related to HBCD and proposed restrictions, the European Union Polystyrene (PS) foam industry is carrying out intensive research on possibilities to substitute HBCD in PS foams. The industry is confident that within five to ten years, at least one appropriate alternative will be available and that the use of HBCD in this important sector will be completely phased out.
