Used primarily as a plasticizer in polymers, especially in polyvinyl chloride (PVC) and other synthetic resins. It imparts excellent low-temperature flexibility, making it suitable for cables, automotive parts, and cold-weather applications. Offers good resistance to water and heat, enhancing durability in outdoor and humid environments. Due to its low toxicity and low volatility, it is suitable for food-contact applications, children's toys, and medical devices. Commonly found in wire and cable insulation, flooring, and coatings where flexibility and stability are required. Also used in some adhesives and sealants to improve workability and performance under stress.
