tert-Butyl 3,5,5-trimethylperoxyhexanoate

tert-Butyl 3,5,5-trimethylperoxyhexanoate (CAS 13122-18-4), also known commercially as tert-butyl per-iso-nonanoate, is an organic peroxide used as a free-radical source in polymer manufacturing.

Where is tert-Butyl 3,5,5-trimethylperoxyhexanoate used?

• Plastics and polymer production: initiator of free-radical polymerization of vinyl and acrylic monomers, controlling molecular weight and conversion rates at mid-range processing temperatures
• Rubber: cross-linking elastomer
• Coatings and adhesives: cure driver for unsaturated resins, enabling controlled hardening profiles suited to industrial application windows
• Sealants and elastomers: selected where a defined half-life temperature aligns with processing or oven-cure conditions
• It improves mechanical strength and heat resistance in finished seals, gaskets, and molded components.

Good to know: Proper storage and temperature control are essential to maintain the stability and efficacy of this reactive chemical intermediate.
