Used primarily as a plasticizer in polyvinyl chloride (PVC) and other polymers to improve flexibility and durability. Offers excellent low-temperature performance, making it suitable for cables, hoses, and automotive parts that must remain flexible in cold environments. Provides good UV and heat stability, beneficial in outdoor applications like roofing membranes and synthetic leather. Also used in lubricants and sealants due to its resistance to water and low volatility. Common in applications requiring low migration and long-term flexibility.
