Material Notes:

Isomag® 70 is a high strength insulating board suitable as an electrical insulator or a thermal barrier material in a variety of industrial applications. Its magnesia silicate based formulation provides a product with an outstanding combination of high compressive strength and low thermal conductivity. Incombustible, Isomag® 175 is totally free of asbestos and may be cut or machined with readily available tools.ApplicationsPlaten press insulation Arc chutes Resistor grids Induction furnaces Pot pads Buss support insulation Foundry bottom boards Blow boards AdvantagesLow heat loss at higher temperatures Low shrinkage at temperature use limit High temperature rating Asbestos and ceramic fiber free Information provided by Pyrotek.
