Diisooctyl maleate

Diisooctyl maleate (CAS 1330-76-3), also supplied under trade designations such as Bisomer D10M and Octomer DIOM, is a reactive diester monomer used across polymer and lubricant manufacturing.

It functions as both a copolymerizable building block and an internal plasticizer, allowing formulators to modify flexibility and processability directly within the polymer backbone.

In plastics and polymer production, it copolymerizes with acrylates, vinyl acetate, and other monomers to produce films, coatings, and adhesives with tailored softness and elongation.

Rubber compounders incorporate it to improve flexibility and processing behavior in specialty elastomers without relying solely on external plasticizer migration during the manufacturing process.

In lubricant formulations, it contributes to viscosity modification and acts as a functional base fluid component in metalworking and industrial lubricant blends for various industrial sectors.

Coatings manufacturers use it as a reactive diluent that reduces viscosity during application while becoming chemically bound in the cured film, effectively avoiding common plasticizer bleed-out.

The product is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for larger procurement volumes. Technical grade is the standard commercial specification.

Buyers should confirm purity, acid value, and color specifications with suppliers, as these parameters directly affect copolymerization performance and the final quality of the chemical application.
