Used primarily as a plasticizer in polymer formulations, this compound enhances flexibility and durability of plastics, especially in polyvinyl chloride (PVC) applications. It improves low-temperature performance and resistance to water extraction, making it suitable for use in cables, films, and flexible tubing. Also employed in coatings and adhesives to modify rheological properties and improve adhesion. Its branched ester structure contributes to good solvency and compatibility with various resin systems.
