  • Applications

    Di-2-ethylhexyl azelate (CAS 103-24-2) is primarily used as a plasticizer for PVC and other polymer systems, improving flexibility and processability of films, coatings, and adhesives. It also functions as a solvent/processing aid in paints, coatings, and inks to enhance flow and film formation. Additionally, it is employed as an intermediate in the synthesis of azelate-based polyesters and polyurethanes. It can serve as an additive in adhesives and coatings to improve flexibility and thermal stability during processing.
