    CAS: 78-63-7

    High-temperature initiator for polymerization of styrene, ethylene, and crosslinking of polyethylene with 10.96% active oxygen content

  • Product Overview

    Perodox® 101 is a high-temperature initiator for polymerization of styrene, ethylene, and crosslinking of polyethylene

    2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane is a high-temperature initiator for the polymerization of styrene, ethylene, and crosslinking of polyethylene. It is also used for the crosslinking of EPDM, EPM, silicone rubber, and the curing of unsaturated polyester resins. Perodox® 101 has a 10-hour half-life temperature of 118°C, making it suitable for high-temperature applications requiring efficient free radical generation.
