Used primarily as a plasticizer in polymer formulations to improve flexibility and workability of plastics, especially in PVC and related materials. Enhances low-temperature performance and elongation properties without significantly compromising thermal stability. Also functions as a lubricant additive, improving viscosity and reducing wear in industrial oils. Its ester structure contributes to biodegradability, making it suitable for environmentally sensitive applications. Employed in coatings and adhesives to modify film formation and improve adhesion to various substrates.
