Calcined Muscovite Mica Tape for fire-resistant cable is an insulation material made of calcined mica paper impregnated with high-quality silicone resin and backed with a reinforcing material. Compared with phlogopite and synthetic mica tape, calcined mica tape can withstand high voltage and significantly higher temperatures, up to 1000℃. Dehydrated calcined mica has a better structure and can withstand higher temperatures.
Features
- Excellent insulating property.
- Resists high temperatures 1000℃.
- Flexible, high-tensile suit for high-speed cable manufacturing.
- Eco-friendly, Free of toxic gases in a fire.
- Pass IEC 60331 and BS 6387 fire-resistance standard tests for high-quality cable.
It has at least 3 hours of excellent electrical insulation at a Temperature of more than 1000℃ and a Voltage of more than 1.0kV/Layer, with no breakdown.
