Recommended Applications

Copolymerization of styrene/butadiene (SBR rubber) and acryl nitrile/ butadiene/styrene (ABS rubber): The emulsion polymerization can be initiated through a redox mechanism at low temperatures. Suitable reducing agents are Fe-salts, sulphites, dithionites, etc. Temperature range: 5 to 20°C Dosing: 0,1 to 0,3 phr

Polymerization of (meth-)acrylates and acrylic resins dispersions: The emulsion polymerization can be initiated through a redox mechanism at low temperatures. Suitable reducing agents are Fe-salts, sulphites, dithionites, ascorbinic acid or sugar, etc. Temperature range: 50 to 80°C Dosing: 0,1 to 0,5 phr

Product Handling and Storage
  • Maximum storage temperature (Ts max) : 25°C
  • Minimum storage temperature (Ts min) : -5°C
  • Storage stability as from date of delivery : 6 months
  • Organic Peroxides are more or less stable products but will decompose under the influence of heat. To minimize a loss of quality during storage, it is important that the recommended maximum storage temperature is not exceeded. If a minimum storage temperature is given, an undesirable process such as a solidification or phase separation, is known to occur below this temperature.
