  • Applications

    Diphenyl phthalate (CAS 84-62-8) is a phthalate ester primarily used as a plasticizer for PVC and other polymers to impart flexibility and elasticity. It is also used as an intermediate in the synthesis of phthalate esters and may function as a processing aid in formulations for coatings, inks, and adhesives to improve processability and film properties. In industrial manufacturing, it serves as a component in polymer formulations, with typical applications in polymers/plastics, coatings/inks, adhesives, and electronics and packaging. Use is subject to local regulations and formulation limits.
