Used primarily as a plasticizer in polymer formulations, especially in polyvinyl chloride (PVC) and related plastics. It improves flexibility, workability, and durability at lower temperatures, making it suitable for flexible PVC applications such as cables, films, and coatings. Exhibits good compatibility with various resins and contributes to enhanced UV stability and low-temperature performance. Also employed in specialty applications like sealants and adhesives where moderate migration resistance and processing stability are required.
