  • Applications

    Di-n-octyl maleate (CAS 2915-53-9) is used as a plasticizer for PVC and other polymers to impart flexibility; it also serves as an intermediate in the production of alkyd and polyester resins and as a processing aid in coatings and inks. It can act as a reactive diluent or comonomer in specialty polymer formulations and may be used in adhesives and sealants where improved flexibility and processing properties are advantageous.
