Description and features
Enox TMCH-90MO (1,1-Di(tert-butylperoxy)-3,3,5-trimethylcyclohexane) is a liquid substance with the chemical formula C17H34O4. It is widely used for the (co)polymerization of styrene, acrylonitrile, acrylates, and methacrylates at temperatures ranging from 90°C to 120°C. Additionally, it facilitates the polymerization of diethylene glycol di(allyl carbonate)-based optical monomers. The appropriate use level of Enox TMCH-90MO depends on the specific cure parameters employed in each application.
Furthermore, 1,1-Di(tert-butylperoxy)-3,3,5-trimethylcyclohexane is also known as TMCH and 1,1-Bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane.
