How It Works
As an organic peroxide, tert-Amyl peroxy-2-ethylhexanoate decomposes by homolytic cleavage when heated near 80-100°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.
