Bis(2-ethylhexyl) Adipate (DEHA)
CAS 103-23-1
Bis(2-ethylhexyl) adipate (DEHA, also commonly referenced as DOA) is an adipate ester plasticizer used in flexible PVC, clear films, synthetic rubber systems, and related industrial formulations. Public product-page sources describe it as a light-colored oily liquid valued for low-temperature flexibility, while final sales specification, packaging, and release values should be confirmed against the supplier TDS, SDS, and COA.
- Provides strong low-temperature flexibility in flexible PVC formulations
- Offers good electrical properties, weathering resistance, and heat stability in plasticized systems
- Can be used alone or blended with other plasticizers such as DOP or DOTP
- Used in clear film and flexible PVC applications where cold flexibility is important

Packaging & storage
Packaging options
- Packaging format to be confirmed during inquiry
- Commercial drum, tote, or bulk options should be matched to the selected supply source
Storage
Store in clean, tightly closed containers under dry, well-managed warehouse conditions. Public handling references for monomeric plasticizers recommend suitable steel or lined storage systems, but product-specific storage details should be confirmed against the supplier SDS/TDS before publication.
Shelf life: A consistent product-specific shelf-life value was not verified from the public sources reviewed for this draft; confirm the final shelf life against supplier sales specification, SDS, or TDS.
FAQ
Frequently asked questions
What is DEHA mainly used for?
DEHA is mainly used as a plasticizer for flexible PVC and related polymer systems where cold flexibility is important.
Is DEHA the same as DOA?
In many public product references, Bis(2-ethylhexyl) adipate is also identified as DOA. Buyers should still confirm naming, grade, and specification alignment during inquiry.
Which details still need confirmation?
Final purity, acid value, color, packaging, storage recommendation, and shelf-life values should be confirmed against the actual supplier documentation before commercial release.
