Description and features

Iniper 117 (tert-butyl peroxy 2-ethylhexyl monocarbonate) is a clear liquid with the chemical formula C13H26O4. Manufacturers primarily use it as a radical initiator to induce polymerization for producing expanded polystyrene (EPS), ethylene, acrylates, and methacrylates. Additionally, it plays a crucial role in crosslinking both natural and synthetic rubbers, as well as thermoplastic elastomers. Moreover, Iniper 117 is particularly effective for curing unsaturated polyester resins at elevated temperatures. Thus, it proves to be a versatile choice across a wide range of applications, enhancing the performance and durability of various materials.
