A new generation of brominated flame retardants: Butadiene Styrene Co-polymer
As HBCD is being phased out globally, manufacturers of thermal insulation foams now have a more sustainable alternative flame retardant.
As an alternative to HBCD an innovative brominated polymeric flame retardant (FR) has been developed to provide effective flame retardant performance in polystyrene foams such as Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS).
These foams, commonly used in building and construction, ensure that homes, offices and public buildings are energy efficient and comfortable, whilst meeting fire safety requirements.
High molecular weight brominated polymer: the efficient, non-hazardous solution
This flame retardant exhibits a superior environmental profile to that of HBCD – being stable, with a high molecular weight. It is also classified as a nonhazardous polymer and as a Polymer of Low Concern(PLC) with officially recognised environment, health & safety characteristics.
Polymeric flame retardants, generally speaking, are inherently sustainable substances. Their high molecular weight makes them unlikely to penetrate through the cell membranes of living tissues. They are therefore not likely to be bioavailable and to bioaccumulate in the food chain.
