Learn what the insulating material mica board is made of

The main component of the insulating material mica board is mica. Mica is a rock-forming mineral with a hexagonal flaky crystal shape. The characteristics are insulation, high temperature resistance, and sericite is widely used in industry, which is widely used in coatings, paints, electrical insulation and other industries.

Mica is a general term for minerals of the mica group. It is an aluminosilicate of metals such as potassium, aluminum, magnesium, iron, and lithium. They are all layered structures and monoclinic systems. The crystals are in the form of pseudo-hexagonal flakes or plates, occasionally columnar.

The layered cleavage is very complete, with glassy luster, and the sheet has elasticity. The refractive index of mica increases correspondingly with the increase of iron content, and can range from low positive protrusions to middle positive protrusions. The variant without iron is colorless in the flakes. The higher the iron content, the darker the color, and the pleochroism and absorption are enhanced.

Mica has many physical and chemical properties, such as its better high temperature resistance, heat insulation, toughness, etc., so its processed mica board, which is mostly used as insulation material for electrical equipment, is made of mica. The finished mica board is not only used in electrical insulation, but also widely used in chemical industries such as building materials, plastics, and rubber.

Muscovite is most used in industry, followed by phlogopite, which is widely used in chemical industries such as building materials industry, fire fighting industry, fire extinguishing agent, welding rod, plastics, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigments, etc.

Mica board Under normal circumstances, the mica content of mica board reaches about 90%, and the other 10% is generally glue and other adhesives. The hard mica board we produce can withstand a temperature of 500 degrees Celsius in a long-term normal working environment, and can withstand a high temperature of 850 degrees Celsius in the short term;

In addition, our phlogopite can work in an average environment of 1000 degrees Celsius, and it is more popular because its breakdown resistance is among the products*.
