Mica washer is a flat circular gasket with concentric circular holes, which is made of mica insulation sheets, including muscovite mica sheets, and phlogopite mica sheets. The mica washers have excellent electrical properties, resist high temperature (500~1000 C), high voltage (20KV/mm T), and abrasion resistance. Mica washers’ normal thickness is 0.3~6mm. Normal diameter tolerance +/-0.2mm.
