Mica Tape

Introduction

Type A: Phlogopite Mica Tape

Phlogopite mica tape for fire-resistant cable, a band（or coil）-shaped electrical and thermal insulation material, consists of the high quality phlogopite mica paper, bonded to supporting materials of non-alkaline glass fabric or polyethylene film, impregnated with high temperature resistant silicone resin.

Fire-resistant wires and cables for power supply lines and control lines of fire-fighting equipment, emergency guide lights and other emergency facilities.

Type B: Calcined mica tape

Calcined mica tape for fire-resistant cable is made of high quality calcined mica paper, alkali free glass fiber cloth for electrician, high temperature resistant silicone resin, baking, drying, cutting and processing at high temperature.

The mica tape has become the first choice of thermal insulation material for ship and nuclear cables with the characteristics of best fire resistance, low smoke and no halogen.

Advantage

Standard：FIRE RESISTANT TEST AS PER IEC60331, BS6387, GB/T 19666.
