Mica board is made of high-quality Muscovite paper, phlogopite paper or synthetic mica paper as the base material,
high-temperature silicone resin as the adhesive, baked and pressed at high temperature.
Hard mica board is specially developed and designed to meet the characteristic requirements of high temperature insulation and electrical insulation.
Excellent insulating properties at high temperature: At 500-1000ºC operating ambient temperature, the voltage breakdown resistance is 15KV/mm; Good tensile property: It can be processed into a variety of shapes without layer separation; Excellent environmental protection performance: The product contains no asbestos, and has less smoke and odors, even smokeless and odorless when heating;Excellent acid and alkali resistance, and oil resistance.
Note: The product less than 2.0mm thickness can be formed by stamping.
The products larger than 2.0mm shall be processed by turning, milling, drilling and other processes.
