  • Applications

    di-N-Octyl Phthalate (CAS 117-84-0) is primarily used as a plasticizer for PVC and other polymers to improve flexibility in films, cables, flooring, and coatings. It also serves as a processing aid and solvent in paints, coatings, adhesives, and inks. It can be used as an additive in rubber compounding to enhance flexibility. It may function as a fragrance fixative or solvent in fragrance formulations. In electronics-related applications, it functions as a plasticizer in insulating materials and encapsulants used in electronic devices.
