Used as a high-performance flame retardant in engineering plastics and electronic materials due to its high bromine content and thermal stability. Its structure enables effective smoke suppression and fire resistance in circuit boards, connectors, and insulating components. Commonly incorporated into polyamides and polyesters where long-term durability under heat and electrical stress is required. Also shows application in coatings for aerospace components where low flammability and resistance to environmental degradation are critical.
