Irganox® 245

Technical Datasheet | Supplied by BASF
Irganox® 245 is a sterically hindered phenolic antioxidant. It contains ethylenebis(oxyethylene)bis-(3-(5-tert-butyl-4-hydroxy-m-tolyl)-propionate). It protects the substrates against thermo-oxidative degradation during manufacturing, processing and end-use. It is odorless, of low volatility, has a good color stability and exhibits high extraction resistance. Provides long-term thermal stability to the polymer. Irganox® 245 is compatible with styrene polymers, particularly impact modified polystyrenes, ABS, MBS, SB and SBR-latices as well as in POM homo- and copolymers, polyurethanes, polyamides, thermoplastic polyesters, PVC and other polymers. It can be used in combination with other additives such as costabilizers (e.g. thioesters, phosphites, phosphonites, lactones), light stabilizers, and other functional stabilizers. Its recommended addition level is 1.0%. It is listed in AICS, DSL, IECSC, EINECS, ENCS, ECL, TSA, PICCS, BUWAL and TSCA. It is approved in many countries for use in food contact applications.

Hansen Solubility Parameters

[17.6, 6.2, 1.5]
?
[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 Irganox® 245. A practical determination of these HSP values would provide higher certainty. Learn More.
