  • Applications

    The chemical 1,1'-(Oxybis(2,1-ethanediyloxy-2,1-ethanediyl)) dioctadecanoate (CAS 142-20-1) is a high-molecular-weight diester widely used as a plasticizer and processing aid for polymers and coatings. In plastics and polymers, it imparts flexibility to PVC, elastomers, and polyesters and can function as a heat-stable lubricant during extrusion or molding. In coatings and inks, it acts as a flow modifier and plasticizer to improve film formation and reduce cracking. In adhesives, it serves as a plasticizer and processing additive to enhance flexibility and workability. In cosmetics/personal care, it may be used as an emollient or conditioning agent in certain formulations. In industrial manufacturing, it can be employed as a high-boiling solvent or lubricant in specialty formulations, supporting processing and performance of systems.
