Chemically, clear mica is totally stable and inert to water, acids, alkalis, oils and solvents. Moreover, it is insensitive to atmospheric variations.
Electrically, clear mica has the following unique combination:
-
high dielectric strength with uniform dielectric stability
-
low power loss at high frequencies
-
excellent resistance to electrical discharge
-
microwave permeability
Thermally, clear mica is relatively flexible, and can be cut, die-cut and/or punched.
