Introduction to the materials used in the production of insulating mica boards

Insulation material mica plate, mica is a rock-forming mineral with hexagonal sheet-like crystals. Sericite mica is widely used in paint, coating, electrical insulation and other industries.

Mica is a general term for the mica family of minerals, which are aluminosilicates of potassium, aluminum, magnesium, iron, lithium and other metals. They are all laminated and monoclinic crystals in pseudo-hexagonal or lamellar, occasionally columnar form.

The lamellar solvation is complete, with a glassy luster and elasticity of the sheet. The refractive index of mica increases with the increase of iron content, from low to positive, and the higher the iron content, the darker the color, while improving the multi-directional color and absorption properties of the material.

Mica has a variety of physical and chemical properties such as high temperature resistance, heat insulation, and toughness. Mica sheets are widely used as insulation materials for electrical equipment.

Mica sheets are not only used for electrical insulation, but also widely used in building materials, plastics, rubber and other chemical industries.

Widely used insulating mica board are 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 rigid mica boards can withstand 500°C under normal long-term operating conditions and 850°C in the short term.

In addition, our gold mica sheets can operate at an average temperature of 1000°C. More popular is its puncture resistance, which is one of the few products with this advantage.
