Silicon Mica

Silicon Mica
SILICON MICA

Mica possesses exceptional properties resisting everything from fire, electricity, chemicals to radiation and at the same time is environmentally safe. Rigid mica sheets consiststing of muscovite or phlogopite mica impregnated with a high temperature silicon binder have unique dielectric, thermal and mechanical properties. Superior in intensity, incombustibility and are flame resistant withstanding temperatures up to 800°C. Applications include but are not limited to thermal protection barriers where mechanical strength and high compression and pressure at high temperature is involved. As insulation between high temperature heated platens and moulds in hydraulic and forging presses. As high temperature insulation of electrode arms and buss-bars in electrical, induction and arc furnaces. Innumerable other uses.

Flexible mica sheets or rolls consisting of muscovite or phlogopite mica impregnated with a high temperature silicon binder are available plain or laminated with glass cloth or ceramic felt. Temperature resistant up to 1000°C (phlogopite). Mainly used as slip plane insulation between the crucible and induction coil in induction furnaces but with a wide variety of other uses.

Mica plates are laminates used in extreme conditions, this product has good properties like high heat resistance, flame resistance, low thermal conductivity, high mechanical strength, easy machineability, good electrical properties, low sensitivity to chemicals, Asbestos free and non-toxic.
