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.
