Mica is a mineral raw material with outstanding dielectric, thermal and physical properties. Mica sheet consisted of 90% high quality Muscovite or Phlogopite mica paper, impregnated with 10% high temperature resistant organic silicon resin after melting and laminating process. They are the ideal alternative for asbestos insulation, and specially developed for providing outstanding thermal and electrical insulation.
Typical application of mica sheet:
- Household application (fan heater, convector, hair dryer etc)
- Industrial heating element (band heater, strip heater)
- High thermal application (induction ovens)
- High voltage insulator
- Industrial sealing and gasket
- Automotive industry
Availability:
