     Calculation based on recommended taping angle 45° and overlaping 50%. More tape width calculation formula as below:
      d——Conductor diameter (mm)
    t——Tape thickness (mm)
    k——Overlapping ratio (%)
    α——Taping angle (°)
    b——Tape width (mm)

    Smaller taping angle increases the taping efficiency but at expense of conductor wrapping tightness which affects negatively for insulating property and extrusion. Recommended taping angle for lowest friction on tape is 45°(+/-5°).

    According to different supporting materials, Firwo®-P phlogopite mica tapes include below mentioned four types: Phlogopite mica tape with single side glass fabric, Phlogopite mica tape with single side PE film, Phlogopite mica tape with double sides glass fabric and Phlogopite mica tape with glass fabric and film backed. For the same thickness of different types, Phlogopite mica tape with single side glass fabric has the most excellent fire-resistant properties due to its higher mica content, but more carefully operation and better taping equipment is required.

    Properties

    ◆ Pass IEC60331 fire resistant standard with single wrapping
    ◆ Pass BS6387CWZ fire resistant standard with double wrapping
    ◆ High speed wrapping up to 70m/min
    ◆ No fabric hairness for coductor wrapping
    ◆ Low fume halogen free
    ◆ 10000 meters continuous efficient wrapping without joint
    ◆ 20% more dielectric strength
