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 B215 is a processing and long-term thermal stabilizer system - is a synergistic blend of PUREfos 168, an organo-phosphite of low volatility and particularly resistant to hydrolysis which protects during the polymer processing and PUREstab 1010 a hindered phenolic antioxidant that contributes synergistically to the processing stabilization and provides long-term thermal stability during service life.

PUREstab 1076 is a sterically hindered phenolic antioxidant. It is a highly efficient and non-discolouring stabilizer for organic substrates such as plastics, synthetic fibres, elastomers, adhesives, waxes, oils and fats. It protects these substrates against thermo-oxidative degradation. PUREstab 1076 is odorless, stable to light and has good compatibility with most substrates, low volatility and high resistance to extraction.
