Recommended Applications

Polymerization of styrene: PEROXAN BU may be used in polymerization and copolymarization of styrene. In a mass process PEROXAN BU can be used to increase polymerization rates. Temperature range: 95 to 125°C Dosing: 0,02 to 0,1 phr

Polymerization of acrylates and methacrylates: PEROXAN DB can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates. Temperature range (solution polym.): 130 to 170°C Dosing: 0,05 to 0,1 phr

Product Handling and Storage
  • Maximum storage temperature (Ts max) : 30°C
  • Minimum storage temperature (Ts min) : 10°C
  • Storage stability as from date of delivery : 6 months
  • Keep packaging tightly closed in a well ventilated place at indicated storage temperature. Keep away from reducing agents e.g. amines, acids, alkalis, heavy metal compounds (e.g. accelerators, driers, metal soaps). Never weigh out in storage room. Oxidizing agent. Decomposes violently under the influence of heat or by contact with reducing agent. Never mix with accelerators. 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.
