Used primarily as a plasticizer in polyvinyl chloride (PVC) and other polymer systems, it improves flexibility, workability, and durability of plastic materials. It is favored in applications requiring good low-temperature performance and resistance to water extraction. Commonly found in wire and cable insulation, flooring, films, and coatings where moderate flexibility and stability are needed. Its molecular structure contributes to better migration resistance compared to smaller plasticizers, enhancing the lifespan of plastic products. Also used in some adhesive and sealant formulations to improve elongation and stress resistance.
