Description

Dicetyl Peroxydicarbonate is a high-purity organic peroxide widely utilized as a polymerization initiator. Its primary value lies in its ability to decompose at moderate temperatures to generate free radicals, enabling efficient and controlled polymer synthesis. This compound is essential for manufacturers in the plastics, coatings, and specialty polymer industries seeking reliable initiators for vinyl monomers and other unsaturated compounds.

Application

• Polymerization Initiator for vinyl chloride (PVC), vinyl acetate, and other vinyl monomers.
• Cross-linking Agent in the production of elastomers and specialty polymers.
• Curing Agent for unsaturated polyester resins in fiberglass-reinforced plastics (FRP).
• Synthesis Intermediate in the manufacture of modified polymers and copolymers.
• Foam Production as a blowing agent activator for expanded polymers.
• Surface Coating Formulations to initiate the curing of acrylic and other coating systems.
