Used primarily as a plasticizer in polymers, especially in polyvinyl chloride (PVC) and related plastics, to improve flexibility, durability, and workability. It serves as an alternative to phthalate plasticizers like DEHP in applications where lower toxicity is desired, such as in medical devices, food packaging, and children's products. Due to its good resistance to extraction by water and oils, it is suitable for use in cables, films, sheets, and coatings. Also employed in adhesives, sealants, and elastomers to enhance low-temperature performance and elongation properties. Its compatibility with a range of resins makes it useful in printing inks and pigment preparations.
