Mica Tape for Fire Resistant Cables with Glass Cloth on Both Sides (FRM2G)

 

         The FRM2G mica tape is a composite of mica paper (phlogopite or synthetic mica) and glass cloth  bound with organosilicon resin It is reinforced by glass cloth on both sides of the tape which makes it a high tensile strength. The main application of FRM2G mica tape is for the insulation of fire resistant cables with plastic sheath and heat resistant coil.
