Description

Bis(4-tert-Butylcyclohexyl) Diperoxycarbonate is a high-purity organic peroxide initiator, a critical component for driving controlled polymerization reactions. Its primary value lies in providing a reliable and efficient source of free radicals, essential for producing polymers with specific molecular weights and properties. This compound is a key raw material for manufacturers in the polymer and plastics industries, particularly for the production of specialty resins, coatings, and high-performance elastomers.

Application

• Primary free-radical initiator for the polymerization of vinyl monomers such as styrene, vinyl chloride, and acrylates.
• Crosslinking agent in the production of unsaturated polyester resins (UPR) for fiberglass-reinforced plastics (FRP).
• Essential component in the synthesis of polyvinyl chloride (PVC) via suspension or bulk polymerization processes.
• Used in the manufacture of acrylic polymers and co-polymers for adhesives, sealants, and surface coatings.
• Key ingredient for curing thermoset resins in composite materials for automotive and aerospace applications.
• Facilitates the production of expandable polystyrene (EPS) beads.
