| Trigonox BPIC-C75 is an initiator (75% active ingredient in odorless mineral spirits) for (co)polymerization of ethylene, styrene, acrylonitrile, acrylates and methacrylates. CAS number: 2372-21-6 EINECS/ELINCS No: 219-143-7 Applications: For Polymer Production: Polymerization of styrene: Trigonox BPIC-C75 can be used for the polymerization and copolymerization of styrene in the temperature range of 95-125°C. During polymerization the temperature is increased in steps. For Thermoset: Trigonox BPIC-C75, tert-butylperoxy isopropyl carbonate, is an aliphatic percarbonate, which is used for the curing of unsaturated polyester resins at elevated temperatures. Trigonox BPIC-C75 is especially developed for the curing of UP resin based Hot Press Moulding formulations (SMC, DMC, BMC etc) in the temperature range of 120 - 170°C. Trigonox BPIC-C75 gives a long shelf life stability of the compound. Trigonox BPIC-C75 can in comparison with Trigonox C, tert-butyl peroxybenzoate, be characterized as a faster and more efficient peroxide. This means a faster and more optimal cure with a lower residual styrene content of the moulded part. In combination with an optimal Low Profile or Low Shrink formulation a very smooth and regular surface of the moulded product can be achieved. The decomposition products of Trigonox BPIC-C75 are low volatile compounds, which makes the peroxide very suitable for the production of e.g. microwave cookware. Information provided by Nouryon |
