New Study Demonstrates Safe Use of Brominated Polymeric Flame Retardant


25 Apr 2019


Climate & Environment
A new paper by Koch et al. entitled “Degradation of brominated polymeric flame retardants and effects of generated decomposition products”  has recently been published in the journal Chemosphere. The same authors published earlier this year two papers on the same subject  . This paper provides a summary of the state on knowledge on the Polymeric FR and the author’s previous work on the substance.
The paper’s conclusion confirms the inherently low environmental and human health risk from the  substance: “Considering that “Polymeric FR” is currently only applied in thermal building insulation, the risk for degradation of this BFR during everyday usage (thus excluding for instance fire) seems comparably low as long as the product is adequately handled at its end-of-life. In this regard and based on the extremely limited amount of studies currently available, it appears that “Polymeric FR” is an important step towards environmentally safer FRs.
The authors also acknowledge that “Different to previous brominated flame retardants, this new group is based on a polymeric structure that could indeed lead to a better environmental profile”.
As noted in their previous papers, the authors find that “Detected degradation products cause almost no acute toxicity, whereas chronic toxicity might be relevant. Nevertheless, as long as polymeric flame retardants are only used in building insulation, the actual risk seems to be rather limited.”
Commenting on the paper, Dr Kevin Bradley of BSEF noted that “Polymeric flame retardants represent an important development in the field of fire safety of materials and products in building isolation since they offer environmentally safer performance”.
BSEF, its member companies and the polymeric value chain acknowledge the need to consider end of life aspects for polystyrene foams containing Polymeric FR. Our value chain remains fully committed to seeking appropriate technology solutions towards meeting Circular Economy principles.
