Hostanox® O 3

Technical Datasheet | Supplied by Clariant
Hostanox® O 3 by Clariant is a bis[3,3-bis-(4’-hydroxy-3’-tert-butylphenyl)butanoicacid]-glycol ester grade. It acts as a phenolic antioxidant and heat stabilizer. It provides long term heat stabilization to polyolefins (PP, HDPE, LLDPE), PA, ABS, styrenic polymers, polyesters, synthetic elastomers, and many other organic substrates especially for applications where the final article comes in contact with extractive media such as water, fat etc. It shows a high resistance to extraction. Hostanox® O 3 is broadly approved in plastics for food contact applications. In combination with sulphur containing co-stabilizers, such as Hostanox SE 10 and Hostanox SE 4, it leads to a pronounced synergistic effect. The minimum shelf life of the product is 3 years.

Hansen Solubility Parameters

[19.4, 0.1, 2]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Hostanox® O 3. A practical determination of these HSP values would provide higher certainty. Learn More.
