Mica Tape for Fire Resistant Bus Duct (FRM2F)

 

         The FRM2F mica tape is a composite of mica paper (phlogopite or synthetic mica paper) and plastic film (PET, PS). The plastic film is bound on both sides of the mica paper with heat resistant binder. It is mainly applied for the heat resistant insulation between metal conductors (copper, aluminum) of the fire resistant bus duct.
