Used primarily as a flame retardant in various polymers and plastics, it enhances fire resistance by inhibiting combustion processes. It is also employed in the production of lubricants and hydraulic fluids due to its thermal stability and low volatility. Additionally, it serves as a plasticizer, improving the flexibility and durability of materials like PVC. In some industrial applications, it acts as a solvent or additive in coatings and adhesives, providing enhanced performance characteristics. Its use is regulated in certain regions due to environmental and health concerns.
