Product Description
Mica Sheet
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.
How is the mica parts operating principle?
When electrical current conveyance metal conducter, the conducter will has very high voltage, high temperature and even fire breaking out.
That demand conducter's holder material - mica parts have good machenical strength, when in high voltage and high temperature operation status.
The mica sheets have good properties as following:
Excellent flame-resistance, have good performence at temperature 500`1000 centigrade.
Good dielectric strength, the high voltage resistance is 20kv/mm
Good machenical strength and toughness, good for machine process the special desgin in microwave oven and other kind electrical heaters.
Eco-friendly, asbestos-free, smokeless or seldom.
