  • Applications

    Diethylhexyl 2,6-naphthalate (CAS 127474-91-3) is used primarily as a non-phthalate plasticizer for PVC and other polymers, helping to impart flexibility in coatings, films, and elastomer systems. It also functions as a processing aid and plasticizer in coatings and inks, as well as in adhesives and sealants. The material is commonly evaluated for electronics-related applications such as PVC-based cable insulation and encapsulants where non-phthalate plasticizers are preferred. It may also serve as a solvent or solvent-compatible plasticizer in specialty textiles finishes or leather coatings. These applications are subject to local regulations and formulation limits.
