Dicumyl Peroxide
Whatsapp Order
Dicumyl Peroxide (DCP) is a widely used organic peroxide with powerful free radical initiator properties. It appears as a white crystalline solid with a characteristic odor and is primarily employed as a cross-linking agent and polymerization initiator in the plastics and rubber industries. Due to its ability to generate free radicals upon thermal decomposition, it facilitates curing and cross-linking of polymers, improving mechanical properties and heat resistance. Dicumyl Peroxide is a key component in manufacturing processes for polyethylene, polypropylene, EPDM rubber, and other elastomers.
