Recommended Applications

PEROXAN DC-40 GS is recommended for the crosslinking of NBR, SBR, EP(D)M, LDPE and EVA. Rubber compounds containing PEROXAN DC-40 GS combine good processing safety with a fair speed of cure. Safe processing temperature (t2): 130°C Typical crosslinking temperature (t90): 170°C The safe processing temperature t2 is defined as the temperature, at which the scorch time is longer than 20 minutes. The typical crosslinking temperature t90 is defined as the temperature at which 90% of the crosslinks in the compound are formed within about 12 minutes.

Product Handling and Storage
  • Maximum storage temperature (Ts max) : 30°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 DC-40 GS.
