Application
It extensively used as linings, gaskets, spacers, covers and backings, setting apart sheet and insulating components in unique industries of family appliance, automobile, metallurgy military, transport and petrochemical.
In positive applications, set up is facilitated via spring-like action, gaskets or self-sealing merchandise with requirement of excessive thermal insulation and mechanical strength.
We offer rigid mica sheets, flexible mica sheets, silicon bonded mica sheet muscovite, silicon bonded mica sheet phlgophite, natural mica sheet and mica washers.
Feature
Outstanding Heat Resistance
Withstands continuous operating temperatures up to 1000°C and resists open flame. Phlogopite grades offer superior thermal endurance for the most extreme environments; muscovite grades deliver excellent performance up to 850°C.
High Dielectric Strength
Exceptional electrical insulation with dielectric strength exceeding 20 kV/mm - ideal for switchgear, transformer barriers, induction furnace linings, and motor slot insulation.
Low Thermal Conductivity
Acts as an effective thermal barrier, minimizing heat transfer in equipment housings, furnace linings, and heat shields. Reduces energy loss and protects surrounding components.
High Compressive Strength
Rigid mica sheets withstand substantial mechanical pressure without deformation, suitable for load-bearing insulation plates and structural insulating components.
Chemical Resistance
Impervious to most chemicals - resistant to oils, greases, solvents, alkalis, and organic acids. Maintains performance in harsh industrial environments.
Asbestos-Free & Eco-Safe
100% asbestos-free, non-toxic, and ecologically safe. Compliant with REACH and RoHS directives.
