Used primarily as a plasticizer in polyvinyl chloride (PVC) and other polymers to improve flexibility, workability, and durability. It is especially valued in low-temperature applications due to its good cold resistance, making it suitable for cables, hoses, and automotive parts that must remain flexible in cold environments. Commonly found in synthetic leather, flooring, and rubber products. Also used in some lubricant formulations and as a component in sealants and adhesives where flexibility and stability are required.
