Used primarily as a plasticizer and lubricant additive in industrial applications. Enhances flexibility and durability of plastics, particularly in polyvinyl chloride (PVC) and other polymers. Improves low-temperature performance and resistance to deformation under stress. Also serves as a processing aid in rubber and synthetic fiber production, reducing friction during manufacturing. Its thermal stability makes it suitable for use in high-temperature processing environments. Additionally, employed in coatings and adhesives to improve adhesion and moisture resistance.
