Let us first explain about mica so that you can have more information.
The chemical composition of mica puts it in the group of aluminum silicates, which have extraordinary physical properties. One of the special capabilities of mica as a mineral is the ability to cut and make very thin pieces with a constant thickness. Its heat tolerance is above 1000 degrees Celsius or 1830 degrees Fahrenheit. Also, mica does not smoke and is a fire retardant and non-flammable. The electrical resistance of mica is above 25 Kv / mm. Other key characteristics of mica are arc resistance and microwave resistance. Mica is stable and resistant to water and chemicals such as acids, solvents, bases and mineral oils and has a high elasticity. It is also very resistant to pressure, impact, tension and bending.
Mica plates are used to make parts, with electromechanical and thermomechanical applications in equipment and tools. Features of mica sheet include excellent heat resistance (up to 1000 ° C), very strong electrical insulation, resistance to the penetration of chemicals, especially oils and greases, low thermal conductivity, high mechanical strength, environmental friendliness and It is asbestos-free and non-toxic.
Some uses of mica sheets:
1- In gas station connections due to high mechanical strength against pressure and resistance to gas leakage
2- In the construction of induction furnaces due to having good electrical insulation properties and permeability to high frequency waves
3- In the molding process of glass industry due to suitable thermal properties and abrasion resistance
4- Mechanical insulation in working conditions with high voltages
