Recommended Applications

Polymerization of styrene: PEROXAN BP-25 WD may be used in polymerization of monostyrene in suspension. Temperature range: 80 to 100°C Dosing: 0,1 to 0,5 phr

Polymerization of acrylates and methacrylates: PEROXAN BP-25 WD can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates. After dissoving in the monomer, the aqueous phase of the peroxide may be separated. Temperature range: 65 to 100°C Dosing: 0,1 to 0,3 phr

Other applications: PEROXAN BP-25 WD may also be used for the (co)polymerization of acrylonitrile, vinylacetate and allyl monomers.

Product Handling and Storage
  • Maximum storage temperature (Ts max) : 30°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.
  • Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN BP-25 WD.
