Mica tape is an electrical insulating material made of glass fiber, polyester film and mica, impregnated and bonded by high temperature resistant resin adhesive, and its melting point is 1200-1300℃. Mica tape is used as a fire retardant insulation layer for cables to ensure that the cables can continue to run for a certain period of time after fire, but pay attention to the following:
The production standard of mica tape shall comply with the international electrical standard IEC 371-3-8:1995
The surface of fire retardant mica tape should be smooth, no burrs, no needles, no scratches, etc
Coiled refractory mica tape should ensure continuous unwinding easy separation, no adhesion phenomenon
mica tape should be best used within 6 months after the completion of production.
