Features:

●Ease and convenience of compounding

●Maintenance of original melt flow

●Low color formation

●Improvement of long-term thermal stability

●Low volatility

●Antioxidant 168 is an organophosphite of low volatility and particularly resistant to hydrolysis protects during processing organic polymers which are prone to oxidation. 

●Antioxidant 1010 is a hindered phenolic antioxidant which contributes synergistically to the polymer's stabilization during processing and provides long-term thermal stability by preventing thermo-oxidative degradation during service life.


Guidelines for use:

In polyolefins: 0.1% ~0.25%, depending on substrate and processing conditions;

Exact dosage must be determined by compositions of the specific polymer system.
