Chemical Name: Dibromoneopentyl Glycol Brand Name: EcoFlame B-261 Equivalent Brand:FR-522 CAS NO.: 3296-90-0 Chemical formula: C5H10O2Br2 Molecular Weight: 261.9 Chemical Structure:
Application: EcoFlame B-261 was a reactive flame retardant, Its high purity is of benefit to the formulator. Thermosetting polyester resins can be formulated over a wide range of compositions to provide a broader selection of resin properties than those available with anhydride flame retardants. Resins formulated with EcoFlame B-261 have high flame retardancy, minimal thermal discoloration and excellent light stability. The high bromine content of EcoFlame B-261 and its ready reaction into polyurethanes make it suitable for use in rigid polyurethane foams. It is increasingly used in CFC-free foam systems designed to meet more stringent standards of flame retardancy.
