Cogetherm is an excellent electrical and heat insulator with good mechanical properties. It is inert to most chemical agents including solvents, acids, bases and mineral oils. It is used as thermal/electrical insulation in induction and arc furnaces, in forging presses, in the glass industry and anywhere a high temperature electrical insulator is needed.
