How It Works

As an organic peroxide, Di(3,5,5-trimethylhexanoyl) peroxide 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.

Primary Applications

Perodox 36 is applied across Emulsion Polymerization, Suspension Polymerization. Typical market segments include Polymer Production.
Its performance profile makes it a trusted choice for formulators who need reproducible,
high-purity raw materials.
