Used primarily as a plasticizer in the production of flexible polyvinyl chloride (PVC) and other polymers, enhancing workability, durability, and elasticity. Commonly found in adhesives, sealants, and printing inks due to its ability to improve adhesion and flexibility. Also employed in rubber products to improve processing and performance characteristics. Its low volatility makes it suitable for applications requiring prolonged flexibility and stability under moderate heat. Occasionally used in coatings and wire insulation materials where resistance to aging and environmental stress is needed.
