Used as a flame retardant in engineering plastics, particularly in polyamides and polyesters, providing excellent thermal stability and hydrolysis resistance. Offers good compatibility with glass fiber-reinforced systems, enhancing mechanical properties while maintaining flame retardancy. Commonly applied in electrical and electronic components such as connectors, switches, and circuit breakers where high performance and safety standards are required. Also utilized in automotive applications including ignition systems and sensor housings due to its ability to withstand high processing temperatures and meet stringent flammability regulations.
