HP5 Rigid Mica Plate for heater consist of approximately 90% muscovite mica paper，phlogopite mica paper or synthetic mica paper, impregnated with high temperature resistant silicone resin.
USED as supporting insulation for resisting wire, heating elements in electric toasters, hair dryers, irons, curlers, electric hot combs, strip heaters, baseboard heaters and for gaskets and in other appliances and applications where excellent resistance to moisture, and thermal, mechanical, and good electrical properties are required.
The mica sheet is CERTIFIED by UL(E248686) and in conformity with IEC371-3-3.

PROCESS:
Gluing Mica Paper– Pressing & Baking – Cutting and Packing

FEATURES:
1. Excellent resistance to heat and even to open flame up to 1000°C.
2. Excellent electrical insulation.
3. High resistance to pressure.
4. Eco-friendly and non-toxic.
