Widely used as a reactive flame retardant in engineering thermoplastics such as polyamides and polyesters due to its high bromine content and thermal stability. It provides excellent flame resistance in electrical and electronic components, including connectors, switches, and circuit breakers. Commonly selected for applications requiring compliance with UL94 V-0 and V-1 flammability standards. Also used in high-temperature polymers like PPO and PPE blends where processing stability is critical. Its methoxy and bromine groups contribute to both oxidative resistance and effective radical quenching during combustion. Suitable for applications in automotive, electronics, and industrial manufacturing where long-term fire safety and material integrity are essential.
