Used primarily as a plasticizer in the production of flexible polyvinyl chloride (PVC) and other polymers. It improves the elasticity and workability of plastics, making them less brittle and easier to process. Commonly found in cables, flooring, films, and coatings where moderate flexibility and durability are required. Also used in some adhesives and sealants to enhance performance under varying temperature conditions. Offers better resistance to water and UV light compared to some general-purpose plasticizers.
