Diisotridecyl adipate

Diisotridecyl adipate (CAS 26401-35-4) is a high-molecular-weight adipate ester plasticizer used primarily in PVC and synthetic rubber compounding.

Where is Diisotridecyl adipate used?

• PVC: primary or secondary plasticizer for wire and cable insulation, automotive interior components, flexible sheeting
• Rubber: improves processing and flexibility in seals, gaskets, extruded profiles
• Metalworking and industrial lubricants: base fluid or functional additive for high thermal stability
• It is also evaluated in specialty lubricant blends where mineral oils raise compatibility or volatility concerns.

Commercial specifications

• Purity confirmed by ester content and acid value testing
• Drum and IBC quantities, with bulk supply options
