Calcined Muscovite Mica Tape for fire-resistant cable is insulation material made of calcined mica paper, impregnated with high-quality silicon resin and backed with reinforcing material, compared with phlogopite mica tape and synthetic mica tape, calcined mica tape can resist high voltage and especially higher high-temperature 1000℃. The dehydration of calcined mica has a better structure and can resist higher temperatures.
Features
- Excellent insulating property.
- Resist high temperature 1000℃.
- Flexible, high-tensile suit for high-speed cable manufacturing.
- Eco-friendly, Free of toxic gases in a fire.
- Pass IEC60331 & BS6387 fire-resistant standard test for high-quality cable.
Have 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.
