Diisooctyl maleate

Diisooctyl maleate (CAS 1330-76-3) is a reactive diester monomer used in polymer and lubricant manufacturing. Also marketed as Bisomer D10M and Octomer DIOM.

Where is Diisooctyl maleate used?

• Plastics and polymer production: copolymerizes with acrylates, vinyl acetate and other monomers for films, coatings and adhesives with tailored softness and elongation
• Rubber compounding: improves flexibility and processing behaviour in specialty elastomers
• Lubricants: viscosity modification and functional base fluid component in metalworking and industrial blends
• Coatings: reactive diluent that reduces viscosity during application and becomes chemically bound in the cured film
• It also acts as a copolymerizable building block and internal plasticizer.

Good to know: Buyers should confirm purity, acid value and colour specifications, as these affect copolymerization performance and final quality.

Commercial specifications

• Drum and IBC quantities; bulk tanker options for larger volumes
