Description

Boric Acid Tris[2,2-Bis[(2,3-Dibromopropoxy)Methyl]Butyl] Ester is a specialized brominated organoboron compound designed for high-performance flame retardancy. This chemical matters because it provides a synergistic combination of bromine and boron, offering efficient flame suppression while potentially improving the thermal stability and processing characteristics of polymer matrices. It is primarily needed by formulators and manufacturers in the plastics, textiles, and coatings industries seeking advanced halogenated flame retardant solutions for engineering polymers, unsaturated polyesters, and epoxy resins.

Application

• As a reactive or additive flame retardant in unsaturated polyester resins for construction panels and automotive parts.
• Flame retardant component for epoxy resin systems used in electronic encapsulants and printed circuit boards.
• Additive for enhancing the fire resistance of engineering thermoplastics like polyamides (nylon) and polyolefins.
• Flame retardant treatment for textile back-coatings and industrial fabrics.
• Component in intumescent coatings and sealants for improved fire protection.
• Specialty additive in wire and cable insulation compounds to meet stringent fire safety standards.
• Potential synergist in flame retardant blends with antimony trioxide or other metal oxides.
