Used primarily as a plasticizer in polymer formulations, especially in polyvinyl chloride (PVC) and related plastics. It enhances flexibility, durability, and workability of the final product. Commonly found in wire and cable coatings, flooring materials, and synthetic leather due to its good low-temperature performance and resistance to extraction by water or oils. Also employed in adhesives and sealants to improve elongation and reduce brittleness. Shows compatibility with a range of organic polymers and is valued for its balance of volatility, migration resistance, and processability.
