RUVA-93 is a non migrating Reactive Ultraviolet Absorber used mainly for high end, long-term exterior performance coatings used in/on polycarbonate plastics..

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.

PURESTAB B225 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.
