Triethylene glycol bis(2-ethylhexanoate)

Triethylene glycol bis(2-ethylhexanoate) (CAS 94-28-0) is a diester plasticizer derived from triethylene glycol and 2-ethylhexanoic acid. It is commercially available under trade names including S 2075, Flexol 3GO, Eastman TEG-EH, and Kodaflex TEG-EH, and is commonly abbreviated as TEG-EH. No E-code designation applies to this substance.

In plastics processing, TEG-EH functions as a primary plasticizer for PVC and cellulosic polymers, improving flexibility by reducing polymer chain interactions at low temperatures. It is also used as a lubricant additive in metalworking and automotive fluids, where its ester structure provides film-forming properties and thermal stability under mechanical stress.

TEG-EH is supplied as a technical-grade liquid and falls under REACH registration requirements for the European market. It is classified under HS code 29147000 for customs purposes. Packaging formats typically include drums and IBC containers; buyers should confirm grade specifications and documentation directly with the supplier.
