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® 565, a hindered phenolic antioxidant, contributes synergistically to polymer stabilization during processing and provides long-term thermal stability by preventing thermo-oxidative degradation. Irganox® B 612 is compatible with styrene homo- and copolymers, polyolefin homo- and copolymer, elastomers such as BR, IR, NBR, SBS, SIS, SEBS, SBR, EPDM, and NR. Its recommended dosage is 0.3-1.0%.
