Mica Tape Calcined Muscovite

Calcined Muscovite Mica Tape consist of high quality muscovite mica paper bonded to reinforced materials of electrical glass cloth or Polyethylene film as the supporting fabric, impregnated with a selected high temperature resistant silicone resin.

Properties
Process of calcination is to heat the selected natural muscovite raw mineral materials with high temperature to improve the stability of chemical composition by removing the water crystallization and impurities which affect negatively the dielectric strength and temperature resistance. Such processing renders calcined muscovite mica tape the following characteristics:
· Extreme temperature resistance
· Superior flexibility suitable for high speed taping on small diameter conductor
· Excellent electrical insulation properties
· Asbestos and halogen free, non-toxic

Application：
Calcined Muscovite Mica Tape are generally applied directly cover conductors, with mica facing the copper to act the ultimate electrical insulation in event of unexpected fire.
Calcined Muscovite Mica Tape is solution for all essential and emergency systems when circuit integrity must be maintained during and after a fire. It is recommended solution for cable including:
· Submarine cables
· Marine cables
· Power cables
· Control cables
· Instrumentation cables
· Signaling cables
