Please refer to the Material Safety Data Sheet (MSDS) for further information on the safe storage, use and handling of DCP.

Application

1.Polymerization of styrene

DCP can be used for the polymerization and (co)polymerization of styrene in the temperature range of 110-165℃. polymerization of styrene in a mass process, DCP can be obtained at increased polymerization rate.

2.Coagent in flame-retardant polystyrene

DCP may also be used as synergistic co-agent in combination with halogen containing flame retardants to produce flame-retardant expandable polystyrene.

3.Rubber crosslink

Rubber compounds containing DCP have good processing safety with a moderate rate of cure.
