Rigid Muscovite Mica sheet

We have different kinds of rigid mica sheets, that is Muscovite mica sheets, Phlogopite mica sheets, and Synthetic mica sheets.

The mechanical strength of the Special design and Heating pressure processed Rigid mica sheet is very high, 150N/mm2.

And mica sheet can resist very high temperatures, Muscovite 500-700 Centigrade, and Phlogopite 700-900 centigrade.

Also high voltage: 17KV/mm.

So the industrial engineers will use the rigid mica sheet as the high-quality insulation material.

Then mica sheet will be punched and processed into different kinds of designs, like the following photo:

That demands the thickness is 0.2-3mm. If more than 3mm, the micas boards need to be processed by CNC, drill, saw…

The heating wire can be wrapped on the gear, threaded through the hole, and fixed on the gap. Then the mica can keep in the good shape at the electric heating element.

There’s an even higher temperature mica sheets, like synthetic mica sheets and calcined mica sheets for customers’ special demand.

We are the factory supplier for the mica sheet. Welcome to visit us.

The following video shows how to cut the mica sheet in our factory.

How to make a mica sheet?

The process step is as follows:

Gluing high-quality muscovite mica paper, phlogopite mica paper, or synthetic mica paper with high-temperature silicon resin.
Heating press the mica paper to mica sheets.
Cutting the mica sheets to size: 1000*600mm, 1000*1200mm, 1000*2400mm
Packing each 50kg mica sheet with PE film, and carton box, then fixing each 1tons mica sheet by wooden pallets.

Mica Sheet Packing & Delivery

Mica sheet packed by PE film, carton box, each box is about 50kgs.

Then about 20 carton boxes/1000kg mica sheets were fixed in wooden pallets (Size: 1200*1000mm).

Then we have our own truck to send the products directly to Shenzhen Port, Shanghai port…
