Diisodecyl adipate

Diisodecyl adipate (CAS 27178-16-1), commonly abbreviated as DIDA, is a high-molecular-weight ester plasticizer and lubricant base fluid derived from adipic acid. It is used across plastics processing, rubber compounding, and industrial lubrication. This chemical is essential where low-temperature flexibility and high-temperature stability are both required in the finished product. In PVC and flexible polymer formulations, DIDA functions as a primary or secondary plasticizer.

It improves cold-temperature performance in cable jacketing, automotive interior components, and sealing profiles. Rubber compounders use it to soften and process compounds destined for automotive seals, gaskets, and tire components. Low-volatility is a critical processing requirement for these applications. As a synthetic base fluid or co-fluid in lubricant blends, DIDA delivers stable viscosity across a wide service temperature range for industrial use.

This makes it suitable for compressor oils, gear lubricants, and metalworking fluids. It also acts as a carrier or solvent in specialty coating and adhesive formulations where compatibility with polymer matrices is a priority. Diisodecyl adipate is supplied as a clear, low-viscosity liquid in drum and IBC quantities. Bulk tanker options are available for high-volume buyers seeking efficient logistics for large manufacturing operations.

Standard commercial grades meet technical and industrial specifications for global trade. Plasticizer-grade material is the most commonly traded form in polymer and rubber markets for various industrial applications.
