Description

Di-(2-Ethylhexyl)Peroxydicarbonate is a highly reactive organic peroxide widely used as a polymerization initiator. Its primary value lies in its ability to efficiently generate free radicals at relatively low temperatures, making it crucial for controlling polymer chain growth and properties. This product is essential for manufacturers in the plastics, coatings, and specialty polymer industries who require precise initiation for vinyl monomers.

Application

• Primary initiator for the polymerization of vinyl chloride (PVC) in suspension and mass processes.
• Key component in the production of low-density polyethylene (LDPE) and other polyolefins.
• Used in the synthesis of acrylic resins and polymers for coatings, adhesives, and sealants.
• Essential for manufacturing polyvinyl acetate (PVAc) and related copolymers.
• Employed in the curing and cross-linking of unsaturated polyester resins for composite materials.
• Facilitates the production of expandable polystyrene (EPS) beads.
• Used in specialty applications for block and graft copolymer synthesis.

Quality Control

Our Di-(2-Ethylhexyl)Peroxydicarbonate is manufactured under strict process controls to ensure batch-to-batch consistency and high reactivity. Each lot undergoes rigorous analytical testing, including assay and active oxygen content determination, to meet precise industry specifications. Certificates of Analysis (COA) documenting purity, concentration, and key safety parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its nature as an organic peroxide and being easily oxidized, it is recommended to store under recommended inert conditions if specified. Keep away from incompatible materials such as strong acids, reducing agents, and other initiators. Always refer to the Safety Data Sheet (SDS) for specific handling and storage instructions.
