PUREFOS 168 is a hydrolytically stable phosphite processing stabilizer. It acts as a secondary antioxidant during plastic processing and protects the polymer matrix by reacting with the hydroperoxides formed at this stage by auto-oxidation. The combination of PUREfos 168 with primary antioxidants provides a synergistic stabilization activity, preventing the overall thermo-oxidative degradation of the material.
PURESTAB 245 is a sterically hindered phenolic primary antioxidant particularly suitable for organic substrates. It stabilize the substrates against thermo-oxidative degradation during manufacturing, processing and end-use. It is of low volatility, has a good color stability and exhibits high extraction resistance.
