Calcined Muscovite Mica Tape for High Temperature Electrical Insulation and Fire Protection Applications

Description

Calcined Muscovite Mica Tape is a high-performance fire-resistant insulation material made from calcined mica paper, impregnated with high-quality silicone resin, and reinforced with backing material.

Compared with phlogopite or synthetic mica tapes, calcined mica tape can withstand higher voltages and extreme temperatures up to 1000°C. The dehydration process of calcined mica improves structural stability, ensuring superior thermal and electrical performance.

It is designed for fire-resistant cables, providing reliable insulation between conductors and the outer sheath, and maintaining functionality during and after fire events.

Features

• Excellent electrical insulation and dielectric strength

• High-temperature resistance up to 1000°C

• Flexible and high-tensile, suitable for high-speed cable manufacturing

• Eco-friendly, free of toxic gases during fire

• Meets IEC60331 and BS6387 fire-resistant standards

• Provides at least 3 hours of insulation at >1000°C and >1.0 kV per layer without breakdown

Applications

• Calcined Muscovite Mica Tape is widely used as a fire-resistant layer in essential and emergency cable systems:

• Power and control cables in high-rise buildings, tunnels, industrial plants, and data centers

• Fire-resistant cables for emergency lighting, fire safety systems, and critical installations

• Electrical systems in oil platforms, aerospace, ships, and military facilities

• It ensures continuous operation and electrical safety during and after fire exposure
