Mica gasket performance characteristics
- Jan 18, 2019 -

Mica gasket, cut or stamped from mica paper or mica plate, mica plate is bonded with mica paper and organic silica gel, heated and pressed, wherein the mica content is about 90%, and the organic silica water content is about 10%. Commonly used mica boards are divided into two types: muscovite and phlogopite. Muscovite and phlogopite have good electrical and mechanical properties, good heat resistance, good chemical stability and corona resistance. The electrical properties of muscovite are better than that of phlogopite, but the phlogopite is soft and its heat resistance is better than that of muscovite. Mica paper can also be composited with metal materials to make mica composite sheet. It is a new type of excellent high temperature sealing material, which is being developed and applied continuously.


It has high dielectric strength and large electrical resistance, low dielectric loss and anti-arcing, anti-corona and other excellent dielectric properties, hard texture, high mechanical strength, high temperature and temperature resistance, acid and alkali resistance. Chemical stability. Good heat resistance, non-combustibility and corrosion resistance.


Mica gasket is suitable for various industrial electric furnaces in the steel, metallurgy, power generation and other industries, power frequency furnace, refining furnace, intermediate frequency furnace, calcium carbide furnace, ferroalloy, yellow phosphorus furnace, electric arc furnace, power plant, electrolytic aluminum power frequency furnace, intermediate frequency furnace, High-temperature insulation such as electric arc furnace and various electrical appliances, electric welders, lightning arresters, electric heating elements and other insulating gaskets.
