How It Works

As an organic peroxide, Bis(2-ethylhexyl) peroxydicarbonate decomposes by homolytic cleavage when heated near 45-55°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.
