Used as a plasticizer in polymer formulations, particularly in polyvinyl chloride (PVC) and related plastics, to improve flexibility and durability. It enhances low-temperature performance and resistance to extraction by liquids, making it suitable for cables, films, and flexible tubing. Also employed in specialty applications requiring good electrical insulation properties and thermal stability. Shows lower migration rates compared to phthalate plasticizers, offering improved longevity in elastomeric and coating systems.
