Mica for induction furnace

Details

Mica for induction furnace is made of mica paper, glass cloths and ceramic paper bonded with silicone adhesive.
Ceramic papers make use of fully bio-soluble fibers, and are compatible with the RCF regulation.
It is mainly used between thermal insulators and coils in induction furnace for coil protection, thermal insulation, and vibration absorption. Furthermore, the slippage nature of mica surface allows for easy disassembly of fire-resistant materials in repair work.

Characteristics

  • (1) Excellent heat resistance and electrical insulation.
  • (2) Comes in rolls for easy installation.

Use

  • (1) Electric induction furnace
