Used primarily as a plasticizer in polymer formulations, especially in polyvinyl chloride (PVC) and related plastics, to improve flexibility, workability, and durability. It enhances low-temperature performance, making materials less brittle in cold environments. Also employed in specialty resins and coatings where improved elongation and impact resistance are required. Its sulfone-based structure contributes to better thermal stability compared to some conventional ester plasticizers, making it suitable for applications with moderate heat exposure. Additionally, it may be used in adhesives and sealants to modify rheology and improve adhesion properties.
