Used primarily as a plasticizer in polyvinyl chloride (PVC) and other polymers to improve flexibility, durability, and workability. It is especially valued in applications requiring good low-temperature performance and resistance to ultraviolet (UV) light and heat. Commonly found in wire and cable insulation, automotive parts, flooring, and coated fabrics. Its low volatility and good migration resistance make it suitable for long-life products. It is particularly noted for its low toxicity, making it suitable for high-safety applications such as food contact materials and children's toys. Also used in adhesives, sealants, and elastomers where enhanced processing and improved mechanical properties are needed.
