  • Applications

    Triethylene glycol dibenzoate (CAS 120-56-9) is commonly used as a plasticizer for PVC and other polymers to impart flexibility and processing ease. It also acts as a processing solvent/plasticizer in coatings, inks, and adhesive formulations, supporting smooth film formation and resin compatibility. In fragrance applications, it serves as a solvent and carrier for aroma compounds and can function as a low-volatility diluent in perfumery formulations. Additionally, it may be used as a plasticizer-compatible additive in various polymer and coating systems, subject to local regulations and formulation limits.
