mica sheet

Brief Description:

A mica sheet is a high-performance material composed of 90% mica—either muscovite, phlogopite, or synthetic mica paper—and 10% silicone resin. Manufactured through a process of baking and pressing at high temperatures, mica sheets are highly versatile. They can be turned, drilled, ground, and milled into various components, making them invaluable in industries such as steel, metallurgy, oil, locomotives, and household appliances. Known for their excellent thermal and electrical insulation properties, mica sheets are a preferred choice for applications demanding durability and reliability.
