A reactive flame retardant contains about 73% of aliphatic bromine. It combines a high bromine content with exceptional stability and is particularly suitable where thermal, hydrolytic and light stability are required. It is mainly used as a reactive intermediate for high molecular weight flame retardants, particularly in combination with phosphorus. Its high bromine content and good compatibility in CFC-free PU system enables high fire retardancy to be reached together with good foam properties in both rigid and flexible PU.
