Diisooctyl adipate

Diisooctyl adipate (CAS 108-63-4), also known as Bis(1-methylheptyl) adipate, is an ester-based plasticizer derived from adipic acid and isooctyl alcohol.

Where is Diisooctyl adipate used?

• Polymer and rubber compounds: flexibility and low-temperature performance
• Industrial fluids: lubrication
• PVC processing: primary or secondary plasticizer for flexible films, sheeting and profiles with good cold-weather performance
• Rubber: elasticity and processability in seals, gaskets and extruded profiles
• Lubricants: viscosity control and friction reduction in synthetic and mineral-based formulations
• Metalworking fluids and gear oils: performance and stability
• Coatings and adhesives: non-migrating, low-volatility plasticizing component
• Buyers should confirm purity specifications and ester content with the supplier.

Good to know: Technical grade is the standard commercial offering. Proper storage and handling are necessary to maintain chemical integrity.

Commercial specifications

• Bulk, IBC and drum packaging
• Purity and ester content vary between producers
