Advantages of Mica
High-temperature resistance
Mica has high resistance to light glowing, which can be used in high-temperature environments.
01
Electrical Insulation
Mica has very good electrical insulation capabilities for use in various types of electrical equipment and electronic components.
Resistance to Corrosion: mica is not corroded by the action of acids, alkalis & solvents.
02
Wear Resistance Mica
Due to the high hardness of mica, it has good wear resistance and can be used as a suitable material or coating for such purposes.
03
Easily separable into thin leaves
Mica can be broken down very easily and has the advantage of forming strong, printable level sheets that can effectively help to create a sexy filler in dry areas as well as thermal insulation.
04
Good Insulation
Mica has an excellent insulation property that is widely used in electrical insulation, insulating gaskets and pipes.
05
Mica Sheet Product advantages
Excellent Temperature Resistance
Mica has a low thermal expansion coefficient and is not prone to expansion or contraction at high temperatures. Even in high-temperature environments,mica sheets can maintain high stability. For example, phlogopite sheets can withstand temperatures up to 1000°C, while muscovite sheets typically withstand temperatures between 500-700°C.
Excellent Electrical Insulation
Mica has a compact molecular structure with very few free electrons, resulting in extremely low leakage current even in high-temperature environments. It is highly resistant to electrical conduction, allowing mica sheets to maintain high dielectric strength and block current effectively, ensuring safe equipment operation in high-temperature conditions. For example, the dielectric strength of phlogopite is typically 20-25kV/mm.
Excellent Chemical Stability:
Mica sheets have strong acid and alkali resistance. The chemical composition and structure of mica make it highly resistant to oxidation under high-temperature conditions. Additionally, mica shows good resistance to most organic solvents, making it an ideal insulating and isolating material for many industrial applications.

How to choose the mica product?
Application scenarios and working conditions
The first step is to identify where the mica product will be used. For example, if it is in a high-temperature environment, such as an industrial furnace or electrical equipment, you need to choose a mica plate or mica tube with high high-temperature resistance.
If it is used for the insulation of wires and cables, mica tape may be a more suitable choice.
For applications that require bending or coiling, mica rolls are more suitable.
Electrical performance requirements
Determine the required electrical performance indicators such as insulation resistance and withstand voltage. Different mica products may vary in electrical properties.
For high voltage or high frequency applications, products with good electrical insulation properties and low dielectric losses need to be selected.
Mechanical performance requirements
Consider the mechanical stress that the product needs to withstand, such as tension, bending, compression, etc. If higher mechanical strength and hardness are required, mica sheets may be a better choice.
If a certain degree of flexibility and bendability is required, mica rolls or tapes may be more suitable.
Size and shape requirements
Select the appropriate size and shape of mica products based on the actual installation space and design requirements.
Ensure mica products fit perfectly with other components and are easy to install and maintain.
Insulating material mica plate, mica is a rock-forming mineral with hexagonal flake crystals. Sericite is widely used in coatings, coatings, electrical insulation and other industries.
Mica is the general name for mica minerals, which are aluminum silicates of potassium, aluminum, magnesium, iron, lithium and other metals. They are all layered and monoclinic crystals, pseudohexagonal or lamellar, and occasionally columnar.
The lamellar cleavage is complete, with glass luster and the sheet is elastic. The refractive index of mica increases with the increase of iron content, from low to medium. The higher the iron content, the darker the color, which also improves the pleochroism and absorption properties of the material.
Mica has various physical and chemical properties such as high temperature resistance, heat insulation, and toughness. Mica board is widely used as insulation material for electrical equipment.
Mica boards are not only used for electrical insulation, but are also widely used in chemical industries such as building materials, plastics, and rubber.
The most widely used insulating mica boards include building materials, asphalt, electrical paper, mica and other industries.
Usually the mica content of a mica board is about 90%, and the other 10% is usually glue and other adhesives. Our hard mica sheets can withstand 500°C in normal operating conditions for the long term and 850°C for the short term.
Additionally, our phlogopite sheets can operate at an average temperature of 1000°C and are even more popular for their puncture resistance, one of the few products with this advantage.
