Trigonox BPIC-CH75
tert-Butyl peroxyisopropyl carbonate, 75% odorless mineral oil solution
CAS Number: 2372-21-6
Physical Form: Liquid
Trigonox® BPIC-CH75 is an initiator for the (co)polymerization of ethylene, styrene, acrylonitrile, vinyl acetate, and (meth)acrylates. It is also a curing agent for unsaturated polyester resins.
Applications
For polymer production: Styrene polymerization: Trigonox® BPIC-CH75 can be used for the polymerization and copolymerization of styrene within a temperature range of 95–125°C. The temperature is gradually increased during the polymerization process. For thermosetting resins: Trigonox® BPIC-CH75, tert-butyl isopropyl carbonate peroxide, is an aliphatic percarbonate used to cure unsaturated polyester resins at high temperatures. Trigonox® BPIC-HC75 was specifically developed for curing UP-based hot-press molding formulations (SMC, DMC, BMC, etc.) within a temperature range of 120–170°C. Trigonox® BPIC-CH75 provides the compound with extended shelf-life stability. Compared to Trigonox® C (tert-butyl peroxybenzoate), Trigonox® BPIC-C75 is a faster and more effective peroxide. This results in faster, optimized curing while reducing the residual styrene content in molded parts. When combined with optimal low-profile or low-shrinkage formulations, it enables very smooth and uniform surfaces on molded products. The decomposition products of Trigonox® BPIC-CH75 are low-volatility compounds, making this peroxide particularly well-suited for the production of products such as microwave cookware.
