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.
