  • Applications

    Polymerization of ethylene: Trigonox 99-C75 is an efficient initiator for the production of Low Density Polyethylene (LDPE). It is used both for tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range. Polymerization of vinyl chloride: Trigonox 99-C75 is used as an initiator for the suspension and mass polymerization of vinyl chloride between 40°C and 65°C. Trigonox 99-C75 is often combined with less active peroxides such as peroxydicarbonates (e.g. Perkadox 16) or diacylperoxides (e.g. Laurox) to increase reactor efficiency.
