Glass Mica Sheet

Glass Mica Sheet is a lamination of uncalcined phlogopite mica paper with a glass cloth. High thermal-grade silicone resin is used as a binder. This highly-flexible material can easily withstand temperatures to the tune of 950°C.

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.
