Mica Tape for Fire Resistant Cables (FRMGF)

 

         FRMGF mica tape is a composite of mica (phlogopite or synthetic mica) paper with glass cloth and polyethylene film. The tape is reinforced by glass cloth on one side and polyethylene film on another side. The tape is bound together with organosilicon resin. The FRMGF mica tape has both  the high strength and flexibility. It is mainly used for the insulation of fire resistant cables and high temperature resistant coils.
