Used primarily as a plasticizer in polymer formulations, especially in polyvinyl chloride (PVC) and related plastics. It improves flexibility, workability, and durability of the final product while offering good low-temperature performance. Commonly found in wire and cable coatings, automotive parts, and flexible films where resistance to heat and UV exposure is required. Also serves as a reactive diluent or crosslinking aid in some resin systems, helping to reduce viscosity during processing without compromising mechanical properties. Its hydrolytic stability makes it suitable for applications exposed to moisture.
