Description

2,2',3,4,4',5,6,6'-Octabromodiphenyl Ether is a highly brominated aromatic compound belonging to the class of brominated flame retardants (BFRs). This compound is valued for its ability to significantly enhance the fire resistance of various polymeric materials by interfering with the combustion process at the molecular level. It is primarily sought by manufacturers in the plastics, electronics, and construction industries who require reliable flame retardancy to meet stringent safety and regulatory standards for their products.

Application

• As a flame retardant additive in high-impact polystyrene (HIPS), ABS resins, and other engineering thermoplastics.
• Enhancing the fire safety of thermosetting polymers used in electrical and electronic components, such as connectors and housings.
• Formulation of fire-resistant coatings and paints for construction materials and textiles.
• Use in polyurethane foams for insulation and automotive applications where flame retardancy is critical.
• Potential application in wire and cable insulation compounds to prevent the spread of fire.
• As a synergistic component in flame retardant systems alongside antimony trioxide.
