Description

Didecyl Peroxydicarbonate is an organic peroxide compound widely utilized as a polymerization initiator. Its primary value lies in its ability to decompose at moderate temperatures to generate free radicals, making it a critical component for initiating and controlling polymer chain growth. This product is essential for manufacturers in the plastics and polymer industries, particularly for the production of polyvinyl chloride (PVC), polyolefins, and various specialty resins. Its controlled decomposition profile allows for efficient polymerization processes, ensuring consistent polymer quality and properties.

Application

• Primary Polymerization Initiator for the suspension and bulk polymerization of vinyl chloride monomer (VCM) to produce PVC.
• Co-initiator or Crosslinking Agent in the production of unsaturated polyester resins and acrylic resins.
• Key component in the manufacture of low-density polyethylene (LDPE) and other polyolefins via high-pressure processes.
• Curing agent for fiber-reinforced plastics (FRP) and composite materials in the automotive and construction sectors.
• Synthesis of specialty polymers, including impact modifiers and processing aids for engineering plastics.
• Surface treatment initiator for coatings, adhesives, and sealants requiring controlled cure kinetics.

Quality Control

Our Didecyl Peroxydicarbonate is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical tests, including assay by iodometric titration, infrared spectroscopy for identification, and gas chromatography for impurity profiling. We adhere to relevant industry safety and quality management standards. Certificates of Analysis (COA) detailing purity, active oxygen content, and key physical parameters are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is below 25°C (77°F). This material is light-sensitive (store away from light) and a strong oxidizer; it must be segregated from reducing agents, acids, bases, and combustible materials. Do not store in excessive quantities. Refer to the Safety Data Sheet (SDS) for complete handling and storage instructions.
