How It Works
As an organic peroxide, Butyl 4,4-di(tert-butylperoxy)valerate decomposes by homolytic cleavage when heated near 50-65°C, generating free radicals. These radicals initiate the polymerization or crosslinking of unsaturated monomers (such as styrene, acrylates, vinyls and unsaturated polyester resins), making it a core radical initiator for thermoset and polymer manufacturing.
