  • Applications

    Polymerization of styrene: Trigonox C may be used for the (co)polymerization of styrene in the temperature range of 100-140°C. In practice, combinations of two or more peroxides with diverging activities are used to reduce the residual monomer content in the final polymer and to increase reactor efficiency. In suspension polymerization processes Trigonox C is often used for reduction of residual styrene content during the final polymerization stage. Polymerization of ethylene: Trigonox C is an efficient initiator for the ethylene polymerization at high pressure in both autoclave and tubular processes. To obtain a wide spectrum of polymerization temperatures, Trigonox C is often used in combination with other peroxides. Depending on reaction conditions, Trigonox C is active in the temperature range of 220-270°C. Polymerization of acrylates and methacrylates: Trigonox C may be used as an initiator for the bulk, suspension and solution (co)polymerization of acrylates and methacrylates in the temperature range of 90-130°C. For Thermoset: Trigonox C, tert-butyl peroxybenzoate, is an aromatic perester, which is used for the curing of unsaturated polyester resins at elevated temperatures. Trigonox C is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, BMC etc.) in the temperature range of 120-170°C. Trigonox C can also be used in combination with high reactive peroxides like Perkadox 16 or Trigonox HM as kicker in formulations for pultrusion in the temperature range of 100-150°C. In combination with a cobalt accelerator (e.g. Accelerator NL-53, 10% cobalt), Trigonox C is also applicable for the cure of UP resins in the temperature range of 70°C and higher. Application area can be: air drying lacquers, diplacquers, filament winding, etc. For Crosslinking: Trigonox C is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins.
