Reduces the risk of damage to the high-voltage coil and leaks caused by cracks in the refractory.
Induction furnace coil and others.
Flexible papers made from mica, muscovite or phlogopite, and silicone resin. Ideal substitutes for asbestos.
Flexmica Paper is a flexible mica-based thermoelectric insulation material recommended for protecting high-voltage coils in induction furnaces. Applied between the coil refractory and the crucible, it acts as a dielectric, thermal and mechanical barrier, reducing stresses caused by the thermal expansion of the crucible, protecting the high-voltage coil against damage caused by contact with molten metal in the event of cracks in the refractory, and helping prevent oversintering of the refractory lining.
There are industrial scenarios where intense temperatures and high electrical voltage not only coexist but operate side by side — such as in induction furnaces, arc furnaces, and electrical transformers. In these environments, choosing the right material goes far beyond simple heat resistance — and it is precisely here that Flexmica stands out.
