Product Detail

Mica sheet


The mica sheet is a plate-shaped insulating material made of high-quality white mica paper, phlogopite paper, and synthetic mica paper, bonded with organic silicon, baked and pressed. The products mainly include rigid mica board for electric heating equipment and soft mica board for electric heating equipment.


Features:


1.Excellent high temperature insulation performance, the highest temperature is over 1000 degrees;

2.Excellent electrical insulation performance, withstand voltage breakdown index up to 20KV / MM;

3.Excellent bending strength and processing performance, high bending strength, and excellent toughness. Punching and drilling into various shapes of gaskets and punches;

4.Excellent environmental protection performance. This product does not contain asbestos, and when it is heated, it emits little smoke and little odor, and even smokeless and tasteless.
