Widely used as a plasticizer in the production of flexible polyvinyl chloride (PVC) and other polymers, providing improved workability and durability. Commonly found in wire and cable coatings, flooring materials, and automotive parts due to its good resistance to heat and UV light. Also employed in industrial applications such as sealants, adhesives, and lubricating oil additives to enhance performance under high-temperature conditions. Its low volatility makes it suitable for use in long-term outdoor applications where stability is required.
