Product introduction
FRMICA FP Hi-silicon enhanced mica tape consists of superior phlogopite mica paper bonded to reinforcedglass fabric, impregnated with high temperature resistant silicone resin. It is special coated with inorganic materials.
It is widely used for all wires & cables as a barrier for circuit integrity to save lives in fire. Its level of performance allows to pass the full range up to the most fire resistance standard such as GB/T19216.31, BS6387, EN 50200, IEC60331 etc.
◆ The special coating gives additional smooth surface of the conductor after taping
◆ Perfect solution for glass and mica problems during high speed taping
◆ Significantly improves the fire resistance performance
◆ Low fume, halogen free, non-toxic

| 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°).
