Used as a flame retardant plasticizer in polymers such as polyvinyl chloride (PVC), polyurethanes, and synthetic rubbers, as well as an anti-wear and flame retardant additive in lubricating oils and hydraulic fluids. It provides both fire resistance and flexibility to the material, making it suitable for wire and cable insulation, automotive parts, industrial coatings, and lubricants. Its thermal stability allows use in high-temperature processing, while its low volatility ensures long-term performance. Commonly found in electrical enclosures, construction materials, and applications where fire safety and durability are critical.
