Diisotridecyl adipate

Diisotridecyl adipate (CAS 26401-35-4) is a high-molecular-weight adipate ester plasticizer used primarily in PVC and synthetic rubber compounding. Its low volatility and cold-temperature flexibility make it a preferred choice for demanding polymer applications.

In PVC formulations, it functions as a primary or secondary plasticizer for wire and cable insulation, automotive interior components, and flexible sheeting. These materials must retain pliability at low temperatures where performance is a priority.

Rubber compounders use it to improve processing and flexibility in seals, gaskets, and extruded profiles. In metalworking and industrial lubricant formulations, it serves as a base fluid or functional additive for high thermal stability.

It is also evaluated in specialty lubricant blends for applications where conventional mineral oils present compatibility or volatility concerns. This versatility makes it a staple in high-performance industrial chemical procurement.

Diisotridecyl adipate is supplied as a clear to pale yellow liquid. Technical grade is the standard commercial offering, with purity specifications typically confirmed by ester content and acid value testing protocols.

The product is available in drum and IBC quantities, with bulk supply options from established ester plasticizer producers. It meets rigorous industrial requirements for consistency and performance in heavy-duty manufacturing environments.
