Application: HBCD mainly used in Expanded and Extruded Polystyrene (EPS and XPS) for thermal insulation foams, in building and construction in order to meet required high fire safety standards. EPS and XPS insulation foams are increasingly important for the European construction sector as they are essential products to help public buildings and homes to be energy efficient. HBCD has no technically suitable alternative in EPS and XPS. It is unique in that it combines high effectiveness with very low levels used thus helping to maintain EPS and XPS insulation properties.
