Used as a flame retardant additive in polymers, particularly in engineering plastics such as polypropylene and polyesters. It enhances thermal stability and reduces flammability without significantly affecting the mechanical properties of the final product. Commonly applied in electronic enclosures, automotive components, and wire and cable materials where fire safety is critical. Its branched structure allows for good compatibility with polymer matrices and low migration over time, making it suitable for long-term performance in demanding environments.
