MICA Paper
Product Definition:
MICA Paper is formed by muscovite paper or phlogopite paper fixed with silicon resin and processed by roll form. It has good dielectric capability and excellent mechanical strength, and often used as the insulating tube form material in all kinds of electric equipment’s, motors, furnaces, electric-arc furnaces, other metallurgy industry equipment’s.
Properties
- Excellent high temperature resistance;
- Excellent insulation properties
- Stable chemical properties
- Excellent mechanical properties
- Excellent permeability and air permeability
Applications
Mica Paper can be used as a base material reinforced with glass fibre cloth, film and other reinforcing materials through silicone resin bonding, and then made into mica insulating materials like mica rolls by high temperature baking and drying.
