Description

Didodecyl Peroxide is a high-purity organic peroxide compound, widely recognized for its role as a polymerization initiator and cross-linking agent. Its controlled decomposition properties are critical for initiating free-radical reactions in the synthesis of polymers and specialty chemicals. This product is essential for manufacturers in the plastics, rubber, and advanced materials industries seeking reliable and efficient initiators for high-temperature processes.

Application

• Primary initiator for high-temperature polymerization of ethylene, styrene, and other vinyl monomers.
• Cross-linking agent for polyethylene (PE) and other polyolefins to enhance thermal and mechanical properties.
• Key component in the production of expandable polystyrene (EPS) and other specialty foams.
• Used in the synthesis of acrylic resins and coatings that require specific cure profiles.
• Employed as a vulcanizing agent in certain elastomer and rubber compounding processes.
• Facilitates graft polymerization reactions for creating modified polymers with tailored characteristics.
