What is Dioctyl maleate?
Dioctyl maleate (CAS 2915-53-9), also known as DOM, is a reactive diester monomer used as a plasticizer and copolymerizable building block in polymer systems.
Where is Dioctyl maleate used?
- Coatings and adhesives: copolymerized with acrylates, vinyl acetate or styrene to modify film flexibility and adhesion
- Sealants and elastomers: improves elongation and low-temperature compliance in cured systems
- PVC and thermoplastics: reactive plasticizer
- Printing inks and packaging adhesives: incorporated into emulsion polymerization to control rheology and substrate bonding in flexible laminates
- Unlike conventional plasticizers, it can be chemically incorporated into polymer backbones, reducing migration and improving long-term performance.
Good to know: Unlike conventional plasticizers, it can be chemically incorporated into polymer backbones, reducing migration and improving long-term performance in finished materials.
Commercial specifications
- Drum and IBC quantities
- Bulk tanker supply from select producers
