Used primarily as a plasticizer in polymers to improve flexibility and workability, especially in resins and coatings. Enhances low-temperature performance and elongation properties in plastics. Also functions as a stabilizer in some formulations, helping to prevent degradation from heat or UV exposure. Its ester structure contributes to improved water resistance and durability in finished products. Employed in specialty applications such as printing inks, adhesives, and sealants where moderate solvency and compatibility with other additives are required.
