How It Works
As an organic peroxide, tert-Butyl peroxypivalate decomposes by homolytic cleavage when heated near 95-115°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 25 is applied across PS, EPS, Bulk Polymerization. Typical market segments include Polymer Production.
Its performance profile makes it a trusted choice for formulators who need reproducible,
high-purity raw materials.
