Dicumyl peroxide (DCP) is a high-purity organic peroxide widely used as a cross-linking and curing agent. It appears as a white, crystalline powder or granules and has excellent stability under controlled conditions. Known for its high efficacy in initiating polymerization and curing processes, DCP is commonly applied in various industrial applications, especially in the production of rubber, plastics, and adhesives.

Key Properties:

• Chemical Formula: C$_{18}$H$_{22}$O$_{2}$
• Molecular Weight: 270.37 g/mol
• Appearance: White crystalline powder or granules
• Purity: Typically >98%
• Melting Point: Around 41–43°C
• Storage: Requires cool, dry conditions and protection from direct sunlight and moisture to prevent decomposition.

Applications:

• Rubber Industry: Used as a cross-linking agent to improve elasticity, durability, and thermal stability.
• Plastic Industry: Acts as a curing agent in the production of polyethylene and polystyrene, enhancing strength and durability.
• Adhesives and Coatings: Serves as an initiator in the polymerization of resins, ensuring strong, durable bonds.
