Irganox® B 225

Technical DataSheet | Supplied by BASF

Irganox® B 225 by BASF is a synergistic processing and long-term thermal stabilizer system. It is basically a blend of IRGAFOX 168 and IRGANOX 1010. Maintains original melt flow and offers low color formation. Provides long-term-thermal stability. IRGAFOX 168, an organic phosphite of low volatility and particularly resistant to hydrolysis, protects the polymers which are prone to oxidation. IRGANOX 1010, a hindered phenolic antioxidant, contributes synergistically to polymer stabilization during processing and provides long-term thermal stability by preventing thermo-oxidative degradation. Irganox® B 225 is compatible with polyolefin and olefin-copolymers such as polyethylene, polypropylene, polybutene and ethylene-vinyl acetate copolymers, engineering plastics, styrene homo- and copolymers, polyurethanes. Its recommended dosage rate in polyolefin is 0.1- 0.25%.
