  • Applications

    Dicyclohexyl phthalate (CAS 84-61-7) is primarily used as a plasticizer for PVC and other polymers, imparting flexibility and reducing brittleness in films, sheets, and molded parts. It is commonly formulated into coatings and printing inks to improve flexibility and processability. It also serves as a plasticizing component in adhesives and sealants, helping to improve adhesion and product flexibility. In polymer systems, it can act as a high-molecular-weight plasticizer for resins such as polyesters and polyurethanes, aiding processing and final flexibility. It is encountered as an intermediate in the synthesis of phthalate ester derivatives and may be used as a processing aid in various formulations. Use is subject to local regulations and formulation limits.
