EcoFlame B-513 was a reactive flame retardant, It combines a high bromine content with exceptional stability and is particularly suitable where thermal, hydrolytic and light stability are required.

EcoFlame B-513 as a reactive intermediate for high Molecular weight flame retardant, particulary in combination with phosphorus, and as a reactive flame retardant for polyurethanes where its high solubility in the system makes it especially useful. It reacts through its single hydroxyl function to form pendant urethane groups.

EcoFlame B-513,high bromine content and good compatibility in CFC-free PU Systems enables high standards of fire retardancy to be reached together with good foam properties in both rigid and flexible PU. Effective Combination of properties may be achived by use of mixtures of it which is monofunctional and EcoFlame B-513 which is difunctional.
