  • Applications

    tert-Amyl peroxy-2-ethylhexanoate serves as a crucial component in various industrial processes, primarily functioning as a free radical initiator.

    Its thermal decomposition properties make it particularly valuable in polymerization reactions and resin curing applications.

    Polymerization Initiator

    Vinyl Polymerization: Used to initiate the free-radical polymerization of monomers like styrene, vinyl acetate, methyl methacrylate (MMA), and acrylates for producing plastics, resins, and coatings.

    High-Temperature Solution Polymerization: Effective for processes requiring initiation in the 90-130°C range.

    Thermoset Resin Curing

    Unsaturated Polyester Resins (UPR): A primary crosslinking agent (curing agent) for UPR in the manufacture of fiberglass reinforced plastics (FRP), including bathtubs, boat parts, and automotive components.

    Gel Coats & SMC/BMC: Used in gel coats and Sheet/ Bulk Molding Compounds to cure the resin matrix, providing surface finish and structural properties.

    Elastomer Crosslinking

    Silicone Rubber: Employed as a crosslinking agent in the peroxide-cure system for high-temperature vulcanization (HTV) of silicone rubber.

    Ethylene-Propylene Diene Monomer (EPDM): Facilitates crosslinking in EPDM rubber for automotive seals, hoses, and roofing membranes.

    Synthesis & Organic Chemistry

    Acts as a source of tert-butoxy and acetyloxy radicals in organic synthesis for oxidation and functionalization reactions.
