  • Applications

    Polymerization of ethylene: Trigonox 121-C75 may be used for the polymerization of ethylene at high pressure in both autoclave and tubular processes. To obtain a wide spectrum of polymerization temperatures, Trigonox 121-C75 may be used in combination with other peroxides. Trigonox 121-C75 is suitable for use in curing unsaturated polyester, vinyl ester and acrylic thermosetting resins in the temperature range of 80 – 130°C (176 – 266°F). Trigonox 121-C75 offers greater reactivity than Trigonox 21, and finds use in a variety of applications including pultrusion, molding compounds and cured-in-place pipe systems. It is also an effective finishing initiator for use in ambient cured systems to lower residual monomer content and improve cure.
