Why is Mica Used for Industrial Thermal And Electrical Insulation?
Mica is a group of minerals that occur naturally in the earth’s crust in igneous rock. There are 37 varieties of mica available, but two varieties most commonly used for industrial applications are phlogopite mica and muscovite mica. Outstanding physical and chemical properties such as high thermal resistance, high dielectric strength, high resistance to moisture, lightweight, and exceptional mechanical properties make it an ideal material to be used for industrial thermal and electrical insulation. Have a look at the key properties of mica material . Thermal insulation Mica is stable at high temperatures. Muscovite mica sheets are stable up to 500 °C (932 °F) whereas phlogopite mica sheets are stable up to 900 °C (1,650 °F). Due to exceptional thermal insulation abilities, mica forms a wide range of insulation products. Rigid mica sheets are used in furnace construction, flexible mica sheets are used in aerospace and automotive industries, mica gasket and mica insulation a
