  • Applications

    Di-2-ethylhexyl maleate (CAS 142-16-5) is primarily used as a plasticizer for PVC and other polymers, providing flexibility and processing efficiency. It also acts as a processing aid in coatings, inks, and adhesive formulations to improve resin mobility and film formation. It can serve as a co-plasticizer in polymer blends to tailor mechanical properties. It is used as an intermediate in the synthesis of related plasticizers and resins, and may be selected as a non-phthalate alternative plasticizer in phthalate-free formulations.
