Mica Board3. RIGID MICA SHEET / MICA PAPER BOARD:
This is a strong rigid Sheet material made by combining Muscovite (M) or Phlogopite (P) Mica Paper with a Silicone resin binder under specific heat and pressure. It has excellent Physical Strength, heat resistance, moisture resistance and electrical properties. It does not emit smoke or odour. Muscovite Mica Paper based material can be used at application. The product is IEC 60371-3-3 compliant.

APPLICATIONS
This is suitable for heating element supports, winding cards and cover plate insulation in domestic appliances, industrial heating elements, high temperature washers, Etc. These are some of the typical high temperature applications
