Technical DataSheet | Supplied by BASF

Irganox® B 225 is a blend of 50% tris(2,4-ditert-butylphenyl)phosphite and 50% pentaerythritol tetrakis[3-[3,5-di-tert-butyl-4-hydroxyphenyl]propionate]. It is basically a blend of 50% IRGAFOX 168 and 50% IRGANOX 1010. Acts as a processing and long-term thermal stabilizer. 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. It 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%. It is suitable for food contact applications. It is listed AICS, DSL, IECSC, ELINCS, ENCS, ECL, TSA, PICCS, BUWAL and TSCA.
