Nouryon Trigonox 117 Thermoset tert-Butylperoxy 2-ethylhexyl carbonate
Categories:	Other Engineering Material
Material Notes:	Trigonox 117 is an aliphatic percarbonate used for curing unsaturated polyester resins at elevated temperatures. Specially developed for UP resin-based Hot Press Moulding formulations (SMC, DMC, BMC). For BMC to reach low values of Volatile Organic Compounds (VOC). CAS number: 34443-12-4 EINECS/ELINCS No: 252-029-5 Applications: Polymerization of styrene: Trigonox 117 can be used as an initiator for the polymerization and copolymerization of styrene in the temperature range between 100°C and 130°C. In a mass process Trigonox 117 can be advantageously used to increase polymerization rates. In suspension polymerization processes Trigonox 117 is an efficient peroxide for reduction of residual styrene concentration during the final polymerization stage. For Thermoset: Trigonox 117 is an aliphatic percarbonate used for curing unsaturated polyester resins at elevated temperatures. For Crosslinking: Trigonox 117 is a monofunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Safe processing temperature: 120°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 150°C (rheometer t90 about 12 min.) Information provided by Nouryon
