  • Applications

    Chemical name: Cyclohexylidenebis(tert-amyl) peroxide; CAS number: 15667-10-4. Cyclohexylidenebis(tert-amyl) peroxide is a dialkyl peroxide used principally as a free-radical initiator in polymer manufacturing and curing systems. In polymer processing, it is employed to initiate radical polymerization of vinyl monomers (e.g., styrene, acrylates) and to promote crosslinking in elastomers and unsaturated polyesters. It is also used as a curing initiator for unsaturated polyester resins in coating, paint, and adhesive formulations that rely on radical crosslinking. In rubber and plastics compounding, it can accelerate cure and crosslinking at appropriate processing temperatures. Depending on local regulations and formulation limits, its use should be evaluated for specific resin or polymer systems.
