  • Applications

    Polymerization of ethylene: Trigonox® 423-CS70 can be applied for the LDPE manufacture in both autoclave and tubular processes. Trigonox® 423-CS70 is a very reactive peroxide, which can be used in combination with less reactive initiators such as tert-Butyl peroxy-pivalate (Trigonox® 25), tert-Butyl peroxybenzoate (Trigonox® C) and others. TA and Io/PE for Trigonox® 423-CS70 are expected to be similar to Cumyl peroxyneodecanoate (Trigonox® 99). Polymerization of vinyl chloride: Trigonox® 423-CS70 is a highly active initiator. It can be used between 40°C and 65°C. Trigonox® 423-CS70 is often combined with less reactive initiators such as peroxydicarbonates (e.g. Perkadox 16) or diacylperoxides (e.g. Laurox) to increase reactor efficiency.
