  • Applications

    Polymerization of ethylene: Trigonox® 125-C70 is an efficient initiator for the ethylene polymerization under high pressure in both autoclave and tubular processes. To obtain a wide spectrum of polymerization temperatures, combinations with other peroxides are applied in practice. Polymerization of vinyl chloride: Trigonox® 125-C70 can be applied as an initiator for the suspension polymerization of vinyl chloride in the temperature range between 50°C and 65°C. Trigonox® 125-C70 may be used in combination with other initiators to increase reactor efficiency.
