Calcined Muscovite Mica Tapes

ASDA-C Calcined Muscovite Mica Tape features calcined muscovite mica, electrical grade glass cloth as reinforcing auxiliary material, and is impregnated with high-temperature resistant silicone resin.

The muscovite is calcined at high temperatures to remove crystal water and non-mica impurities that could affect the pressure and temperature resistance. The water permeability of the calcined muscovite mica to organic silica is much higher than phlogopite or synthetic mica.


ASDA-C is Class A fire-resistant and electric insulation material for cable wrapping, electrical winding insulation, winding wire coating insulation, windmill/power generators, high-voltage motors, and transformers.

At 850℃ to 900℃ or 1562℉ to 1652℉, under a voltage of 600V to 1000V, breakdown time >90 minutes.

Fire Resistance: Class A, BS6387 / IEC 60331, GB/T19216


Key Features

  • High flexibility is suitable for efficient high-speed wrapping.

  • A high level of fire resistance can reduce the wrapping cost: single-layer wrapping can pass IEC60331; double-layer wrapping can pass BS6387C.

  • High product qualification rate: the wrapped appearance is smooth and beautiful without burrs.

  • Environment-friendly: fluorine-free and halogen-free; no smoke or carbon deposition at burning.
