1,3,5-Tris(3,5-dibromophenyl)benzene is primarily used as a flame retardant in various polymer materials. Its high bromine content makes it effective in reducing the flammability of plastics, textiles, and other synthetic materials. It is often incorporated into electronic components, construction materials, and automotive parts to enhance fire safety. Additionally, it is utilized in coatings and adhesives where flame resistance is a critical requirement. Its stability and compatibility with polymers make it a valuable additive in industries prioritizing fire protection.
