Used primarily as a plasticizer in polymer formulations to enhance flexibility and workability of plastics, especially in polyvinyl chloride (PVC) and related resins. It improves low-temperature performance and elongation properties without significantly compromising tensile strength. Also functions as a stabilizer and processing aid in coatings, adhesives, and sealants. Its branched alkyl chain structure contributes to good migration resistance and compatibility with a range of organic matrices. Employed in specialty applications where low volatility and enhanced durability are required.
