Irganox B 225 – a processing and long-term thermal stabilizer system – is a synergistic blend of Irgafos 168 and Irganox 1010.


Irganox B 225 is used in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polybutene and ethylene-vinylacetate copolymers. The blend can also be used in other polymers such as engineering plastics,  styrene homo-and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates. Irganox B 225 can be used in combination with light stabilizers of the Uvinul, Tinuvin and Chimassorb range.


Irganox B 225 is a convenient blend addressing a range of stabilization needs. The relatively high phenolic antioxidant content of Irganox B 225 addresses applications requiring more long-term thermal stability. In the recommended applications Irganox B 225 provides significant benefits, such as

• long-term thermal stability

• maintenance of original melt flow

• low color formation

Irgafos 168 – an organophosphite of low volatility and particularly resistance to hydrolysis – protects during processing organic polymers which are prone to oxidation. Irganox 1010 – a hindered phenolic antioxidant - contributes
synergistically to the stabilization of the polymer during processing and provides long-term thermal stability by preventing thermo-oxidative degradation during service life. Performance can be improved in synergistic combinations
with other BASF additives (e.g. thioethers). Blends of Irganox 1010 and Irgafos 168 with Hydroxylamine FS042 are particularly effective.
