Recommended Applications

Polymerization of ethylene : PEROXAN PA-50 is used for high pressure in both autoclave and tubular processes, usually in combination with other peroxides of varying degrees of activity. Temperature range: 215 to 250°C Light-off temperature at 2300 bar: 220°C

Polymerization of styrene: PEROXAN PA-50 may be used in polymerization and copolymarization of styrene. In a mass process PEROXAN PA-50 can be used to increase polymerization rates. In suspension polymerization processes, PEROXAN PA-50 is often used for reduction of residual styrene content during the final polymerization stage. Temperature range: 100 to 130°C Dosing: 0,02 to 0,1 phr

Polymerization of acrylates and methacrylates: PEROXAN PA-50 can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates. Temperature range: 100 to 170°C Dosing: 1 to 3 phr

Other applications: PEROXAN PA-50 may also be used for the copolymerization of acrylonitrile.

Product Handling and Storage
  • Maximum storage temperature (Ts max) : 10°C
  • Minimum storage temperature (Ts min) : -15°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.
  • Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN PA-50.
