  • Applications

    Oxydiethylene bis(2-ethylhexanoate) (CAS 72269-52-4) is a diester used primarily as a plasticizer and processing aid in polymers and coatings: it provides flexibility and lowers the softening point for PVC, polyurethane, and acrylic resins. It also functions as a solvent or co-solvent in industrial coatings, inks, and adhesives formulations, aiding pigment dispersion and film formation. As an intermediate in organic synthesis, it can be converted to other diester derivatives or used as a softening component in polymer blends. It can serve as a processing aid in elastomer formulations and as a compatibility-promoting additive in various polymer systems. In cleaning formulations, it can act as a high-boiling solvent or co-solvent to improve solvency for oils and residues. In electronics or cable compounds, it is sometimes included as a plasticizer component to adjust flexibility and processability of insulation resins.
