What Are Mica Sheets Used For?
The major use of mica sheets and discs are as electrical insulators in electronic equipment, thermal insulation, gauge “glass”, windows in stove and kerosene heaters, dielectrics in capacitors, decorative panels in lamps and windows, insulation in electric motors and generator armatures, field coil insulation, and magnet and commutator core insulation.
Popular use of mica disks is the protection against erosion of the sight glasses and flat glasses in the flow viewfinders. Glass exposed to aggressive fluids, boiler water, steam, and working at high temperatures and pressures are subject to erosion visible as a dull surface of the glass. Glass layer losses cause a decrease in its strength and shorten the period of safe operation.
Mica discs offered by us are die cut or lathe cut round discs, which find usage in liquid level indicators, breathing apparatus, communication devices, fuses and other end products.
Examples of applications:
- Aluminosilicate and borosilicate glass protection against steam and water,
- Glass protection from acids, reactive and corrosive substances.
- Mica disks eliminate the risk of cracking, fractures and splinters of glass.
- Widely used for home appliances such as electric hair-dryer, toaster, microwave oven, warmer, etc.
