INTRODUCTION
Mica is a group of 37 phyllosilicate minerals that occurs naturally in igneous and metamorphic rock. It is crystallized in the monoclinic system, with a tendency towards pseudohexagonal crystals. Out of 37 minerals, only two, phlogopite mica and muscovite mica are used for industrial thermal and electrical insulation applications. www.aximmica.com

THERMAL INSULATION
Mica is used for industrial thermal insulation in a wide range of applications. Mica sheets are stable up to 1000 degrees Celsius, and build-up mica sheets are stable up to 1500 degrees Celsius. High thermal resistivity makes mica ideal to be used in high-temperature environments.
ELECTRICAL INSULATION
Mica has an amazing dielectric strength of up to 20000 v/mm. Not just that, mica is also stable at high temperatures. It makes mica an ideal material to be used in a wide range of industrial electrical insulation applications. Mica dielectric strength varies according to temperature. Mica sheets have a dielectric strength of 25 VK/mm at 20°C, 13 VK/mm at 400°C, and 10 VK/mm at 600°C.
