Mica Tape for fire-resistant cable (MT-PGA)

Mica Tape is a kind of insulation material made of phlogopite mica paper or muscovite mica paper mixed with silicon resin and other binder and glass fiber cloth after baked and cut, can resist high voltage and especially high temperature.

High quality mica paper bonded to an electrical grade glass fiber cloth (G type) as the reinforce material, impregnated with a specially selected high temperature resistant silicon resin.


1. Excellent insulating property.
2. High temperature resistant.
3. Flexible, high tensile suit for high speed cable manufacturing
4. Eco-friendly, Free of toxic gases in fire.
Have at least 3 hours excellent electrical insulation at Temperature more than 850℃ and Voltage more than 1.0KV, with no breakdown.


MICA TAPE(MT-PGA) is used as fire resistant layer between conductors and out sheath. They are suitable for all essential and emergency system include power and control cable, must be maintained good property and function during and after a fire.


According to mica paper and support agent, mica tape has following different types.

Main Model Mica Reinforce Material Structure
MT-PGA Phlogopite Glass fiber cloth Signer Side (A)
MT-SGA Synthetic Glass fiber cloth Signer Side (A)
MT-CGA Calcined Glass fiber cloth Signer Side (A)
MT-PGFD Phlogopite Glass fiber cloth & PET Film Double Side (D)
Add: MTS-PG: Mica Tape in Spool Series.  (As photo show)
