Used primarily as a plasticizer in polymer formulations, this compound enhances flexibility, workability, and durability of plastics, especially in polyvinyl chloride (PVC) and other synthetic resins. It improves low-temperature performance, making materials less brittle in cold environments. Commonly found in flexible films, coatings, adhesives, and sealants, it also contributes to better processability during manufacturing. Its molecular structure supports thermal stability and resistance to water extraction, making it suitable for outdoor and industrial applications where longevity and performance under stress are critical.
