Blend of antioxidants B215

Antioxidant blends,Blend of 33% Antioxidant 1010 and 67% Antioxidant 168, synergistic processing and long term thermal stabilizer system.


It is a blend of antioxidants which contains 67% and Antioxidant 168:an organophosphite of low volatility and particularly resistant to hydrolysis which protects organic polymers which are prone to oxidation during processing and 33% Antioxidant 1010: a hindered phenolic antioxidant which contributes synergistically to the polymer’s stabilization during processing and provide long term thermal stability by preventing thermo-oxidative during service life.
