Glass / Mica Folium
Higher temperature-endurance of 1200° C can be achieved by laminating an additional backing of ceramic-felt on the glass cloth side making it a Mica/Glass/Ceramic Folium.
These do not emit any smoke or odor upon heating up. They have excellent electrical-resistance and high thermal-conductivity increasing the overall efficiency of the furnace.
APPLICATION
Slip-plane insulation in furnaces protecting the coil and high-temperature resistant refractory linings and relining of crucible furnaces. Apart from providing electrical and thermal insulation it also acts as a gas-diffusion barrier.
Mica is an excellent substitute for asbestos due to its many working-environment health-benefits and green biodegradable properties. Mica ensures maximum worker safety and greatly reduces the furnace down time due to the accumulated sintered mass.
