Used as a plasticizer in polymer formulations to improve flexibility and workability, especially in coatings, adhesives, and synthetic rubbers. Enhances low-temperature performance and elongation properties of films and molded parts. Also functions as a solvent and processing aid in cellulose-based systems due to its good solvating ability and moderate evaporation rate. Its branched ester structure contributes to improved compatibility with a range of resins while reducing crystallization tendencies in final products.
