Used primarily as a plasticizer in polymer formulations to enhance flexibility and workability of plastics, especially in polyvinyl chloride (PVC) applications. It improves low-temperature performance and increases resistance to heat and UV degradation. Commonly found in wire and cable coatings, flooring materials, and flexible films where durability and long-term stability are required. Also utilized in adhesives and sealants to improve tack and elongation properties. Its branched alkyl chain structure contributes to good solvating ability and compatibility with various resin systems.
