Polymerization of ethylene: Trigonox 21-C50 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 styrene: In suspension polymerization processes, Trigonox 21-C50 can be used for the polymerization of styrene at approximately 90°C. Trigonox 21-C50 has an activity comparable with dibenzoyl peroxide (Perkadox L-W75). Typically, Trigonox 21-C50 is used in combination with initiators such as tert-Butyl peroxybenzoate (Trigonox C).
Polymerization of acrylates and methacrylates: Trigonox 21-C50 is an efficient initiator for the solution (co)polymerization of acrylates and methacrylates in the temperature range of 65-100°C, amongst others for the manufacture of coatings. Trigonox 21-C50 can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methacrylates.
Initiator (50% active ingredient in odorless mineral spirits) for (co)polymerization of ethylene.
