  • Applications

    For Polymer Production the following applications: Polymerization of styrene: Trigonox T can be used for the polymerization and copolymerization of styrene in the temperature range of 95 -125°C. Polymerization of acrylates and methacrylates: Trigonox T can be used as initiator for the solution (co)polymerization of acrylates and methacrylates in the temperature range of 130 170°C, amongst others for the manufacture of coatings. Trigonox T can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methacrylates. For Crosslinking: Trigonox T is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins. Rubber compounds containing Trigonox T have excellent scorch safety, safe processing temperature: 135°C (rheometer ts2 > 20 minutes), typical crosslinking temperature: 175°C (rheometer t90 about 12 minutes) and one of the decomposition products of Trigonox T has a distinct sweet smell.
