Used primarily as a plasticizer in polyvinyl chloride (PVC) and other polymers to improve flexibility, durability, and low-temperature performance. Commonly found in wire and cable insulation, flooring, films, and synthetic leather due to its good electrical properties and resistance to water extraction. Also utilized in sealants, adhesives, and coatings where flexibility and weather resistance are required. Exhibits good compatibility with many resins and provides enhanced UV and heat stability in outdoor applications.
