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. It improves flexibility and low-temperature performance in polymer and rubber compounds.

This chemical provides essential lubrication in industrial fluid formulations. In PVC processing, it functions as a primary or secondary plasticizer to achieve flexible films, sheeting, and profiles with good cold-weather performance.

Rubber compounders use it to improve elasticity and processability in seals, gaskets, and extruded profiles. This is particularly useful where low-temperature flexibility is a critical specification for the final product.

In synthetic and mineral-based lubricant formulations, it contributes to viscosity control and reduces friction. It is commonly utilized in metalworking fluids and gear oils to enhance overall performance and stability.

It also appears in specialty coatings and adhesives where a non-migrating, low-volatility plasticizing component is required. This ensures the longevity and durability of the adhesive bond or coating layer over time.

The product is supplied as a clear, low-viscosity liquid in bulk, IBC, and drum packaging. Technical grade is the standard commercial offering, suitable for industrial plasticizer and lubricant applications.

Buyers should confirm purity specifications and ester content directly with the supplier, as these vary between producers. Proper storage and handling are necessary to maintain the chemical integrity of the material.
