Mica Paper Sheet


Mica Paper Sheet

Mica Paper Sheet consist of muscovite or phlogopite mica paper, impregnated with high heat resistant silicon resin. Several layers of impregnated mica paper are consolidated under heat and high pressure to form rigid plates, in this process, the binder is completely cured. Mica Paper Sheet product is IEC 60371-3-3 compliant. The Mica Paper Sheet maintains their self-supporting characteristics even after being heated.
