Description and features
Iniper 117 (Tert butyl peroxy 2-ethylhexyl monocarbonate) is a clear liquid which has C13H26O4 as chemical formula. It is mainly used as radical initiator to induce polymerization for the production of EPS (expanded polystyrene), ethylene, acrylates and methacrylates. Further it is used for the crosslinking of natural and synthetic rubbers as well as thermoplastic elastomers. Lastly it is used for the curing of unsaturated polyester resins at elevated temperatures.
