Used primarily as a plasticizer in polymers, especially in polyvinyl chloride (PVC) and other plastics to improve flexibility, workability, and durability. It is valued in applications requiring low-temperature performance and good resistance to water and UV exposure. Commonly found in wire and cable coatings, automotive parts, and flexible films. Its structure contributes to enhanced compatibility with resin systems and reduced migration in finished products. Also used in specialty coatings and sealants where extended flexibility and aging stability are required.
