Description

2,2'-Dichlorodibenzoyl Peroxide is a specialized organic peroxide primarily used as a high-activity initiator for polymerization reactions. Its value lies in its ability to efficiently generate free radicals at moderate temperatures, enabling precise control over polymer chain formation and molecular weight. This compound is essential for industrial chemists and manufacturers in the plastics, polymer, and specialty chemical synthesis sectors who require reliable and consistent initiation for producing high-performance materials.

Application

• Polymerization Initiator: A key free-radical initiator for the production of polyvinyl chloride (PVC), polystyrene, and other vinyl polymers.
• Cross-linking Agent: Used in the curing and cross-linking of unsaturated polyester resins and silicone rubbers to enhance thermal and mechanical properties.
• Specialty Chemical Synthesis: Facilitates specific organic synthesis reactions requiring a controlled radical source.
• Curing Agent for Composites: Employed in the manufacture of fiber-reinforced plastic (FRP) composites for automotive and marine applications.
• Adhesive & Sealant Production: Acts as a curing initiator in the formulation of high-strength industrial adhesives and sealants.
