Used as an effective flame retardant additive in polymers, particularly in polycarbonates and engineering plastics. It helps improve thermal stability and reduces flammability without significantly affecting the mechanical properties of the material. Commonly applied in electronics, automotive components, and electrical enclosures where fire safety is critical. Also functions as a plasticizer in some resin systems, enhancing processability and flexibility. Shows good compatibility with aromatic polymers and is often preferred in applications requiring high transparency and color stability.
