Used primarily as a reactive brominated flame retardant in engineering plastics and thermosetting resins. It offers excellent thermal stability and flame resistance in high-performance polymers such as polyamides, polyesters, and epoxy systems. Commonly found in electrical and electronic components, including circuit boards, connectors, and insulating materials, where long-term flame protection and structural integrity at elevated temperatures are required. Its polymeric structure reduces leaching and volatility, making it suitable for applications demanding environmental and regulatory compliance. Also utilized in composite materials for aerospace and automotive industries due to its ability to maintain mechanical properties while providing fire safety.
