DCP 40C
DicumylPeroxide 40% on Calcium Carbonate
Calcium carbonate is as an inert substance in the formula of the crosslinking reagent. It also is a substance to prevent the ph value of crosslinking reagent large than 7. it can retard the DCP decomposition. It can help the DCP dispersing when DCP disperse into the rubber as a crosslinking reagent as well.

Applications
1.Cross linking agent for EVA foam.
When cross-linked by DCP, the foamed EVA possesses special properties better than that of other foamed materials in lightweight, coloration and abrasion-resistance. It has become as an essential ingredient for making sandals, slippers and shoe soles.
2.Cross linking agent for polyethylene insulated electric cable (XLPE cable) In the production of insulated electric cables, polyethylene after cross-linked by DCP, can resist high temperature caused by electric current in the wire. It has become a very important material in the field of wire and cable.
3.Vulcanizing agent for EPR & EPT.
ERP & EPT are newly developed synthetic rubbers which have given indication of sufficient quality to merit careful consideration for wire and cable coating and conveyor belts. EPR cannot be cured by sulfur, however can be efficiently cured by DCP or other organic peroxides. DCP becomes a necessity in improving the heat resistance capability of EPT.
