DCP is mainly used as vulcanizing agent of synthetic rubber such as natural rubber, ethylene propylene diene monomer (EPDM), nitrile rubber, initiator of polymerization, and crosslinking agent of polyethylene and EVA resin. Crosslinked polyethylene used as cable insulation material, not only has excellent insulation and processing properties, but also can improve its heat resistance. Use vulcanizing agent DCP2.4 for 100 parts of polyethylene. Vulcanizing agent DCP can make the ethylene vinyl acetate copolymer () foam material form fine and uniform bubbles, and improve the heat resistance and weather resistance of the product. In addition, it can also be used as curing agent of unsaturated polyester, polypropylene melt index regulator, etc.
It is widely used in wire and cable, EPS, shoemaking, flame retardant coating and other industries.
