Calcined
muscovite
mica tape.
Designed for fire-resistant wires and cables.
Reliable insulation where circuit integrity matters.
MICA PAPER / GLASS FABRIC / SILICONE RESINThree materials.
One protective layer.
Calcined muscovite mica paper bonded to non-alkaline glass fabric with high-temperature resistant silicone resin. This construction combines electrical insulation and thermal stability with mechanical strength and flexibility.

Standards & application.
The supplied datasheet lists a pass against IEC 60331:1999 and references IEC 60331, BS 6387 CWZ and GB/T 19216.
Performance depends on the complete cable.
Tape selection, number of layers, overlap and cable construction affect fire-test performance. A tape datasheet does not establish certification of a finished cable. Contact us to discuss the requirements for your design.
