Natural Mica Tape
Application
Nature phlogopite tape is being twined directly round the conductors(IEC-331)orused as superior flame barrier wrapped up the protect cover(iec-332,ul-910 plenum flame test)It is a perfect fire resistant component in fire-resistant wire&cable maufacture according to IEC-371-2-8.
SpecificationSupply as rolls up to 300~500~1000 m,width of 6~900mmand the standard core diameter is at Φ52mm,Φ76mm.
