It is basically a blend of 80% IRGAFOX 168 and 20% IRGANOX 1010. Acts as a synergistic processing and long-term thermal stabilizer. Maintains original melt flow and offers low color formation. Provides long-term-thermal stability. 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 and elastomers. Its recommended dosage rate in polyolefin is 0.1- 0.25%. It is registered in AICS, DSL, IECSC, ELINCS, ENCS, ECL, TSA, PICCS, BUWAL and TSCA.
