Dioctyl succinate

Dioctyl succinate (CAS 14491-66-8), also known as dicapryl succinate, is a diester of succinic acid used in industrial formulations as a plasticizer, lubricant, and carrier solvent.

Where is Dioctyl succinate used?

• Plastics and polymer processing: plasticizer improving flexibility and workability in PVC and similar resin systems
• Coatings and adhesives: carrier solvent or softening agent to adjust viscosity and film properties without compromising adhesion
• Lubricants and metalworking fluids: lubricity, reducing wear at metal contact surfaces
• Automotive specialty lubricants and sealant compounds use ester-based fluids for thermal stability and elastomer compatibility.

Commercial specifications

• Packaging: drums to IBC totes
• Bulk quantities available
