Description

2,2',4,4',6,6'-Hexabromobiphenyl is a fully brominated derivative of biphenyl, characterized by its high bromine content and aromatic structure. This compound serves as a highly effective flame retardant additive, providing excellent thermal stability and fire suppression properties to various polymer matrices. It is primarily utilized by manufacturers in the plastics, electronics, and construction materials industries seeking to enhance the fire safety of their products and meet stringent regulatory standards for flame retardancy.

Application

• As a flame retardant additive in engineering thermoplastics such as polycarbonate (PC), acrylonitrile butadiene styrene (ABS), and high-impact polystyrene (HIPS).
• For enhancing the fire resistance of epoxy resin systems used in printed circuit boards (PCBs) and electronic encapsulants.
• In the formulation of fire-retardant coatings and paints for construction materials and textiles.
• As a component in specialty polymer blends for wire and cable insulation requiring high flame retardant ratings (e.g., UL 94 V-0).
• For research and development purposes in the synthesis of novel brominated flame retardants and related chemical intermediates.
• In laboratory studies on the environmental fate and analysis of persistent organic pollutants (POPs).
