Products Description
Insulated Mica Sheet comes in the form of rigid laminated sheet after laminating, pressing and baking process, consists of quality muscovite,phlogopite or synthetic mica paper impregnated with high temperature resistant organic silicon resin as binding agent.
Insulated Mica Sheet maintain their insulating properties at temperatures up to 700°C, making them suitable for applications such as high-temperature motors and transformers, and power equipment.
Insulated Mica Sheet has an insulation resistance of over 500 MΩ and superior arc resistance, ensuring safe operation in high-voltage electrical equipment.
Note：We provide customized services of various thicknesses and sizes, from 1mm to 50mm, we can make them. If you have purchasing needs for mica boards, you can contact us.
