What is a mica sheets?

Mica sheets are also referred to as mica plates and boards; occasionally, thin mica sheets are called mica paper. They are mainly made from glued mica paper, stacked several pieces to a unique thickness, separated by woven glass fiber cloth, and then processed in a heating press machine into mica sheets.

The thin mica sheets are primarily used to punch mica gaskets, which serve as heating wire holders in machines such as electric hair dryers and microwave ovens. The thick, rigid mica sheet will be CNC-processed into mica parts. It has high strength and can resist both high temperatures and high voltage.

Are Mica Sheets for sale?

The Mica sheets include a Rigid mica sheet and a Flexible mica sheet. They used a different kind of silicone resin and Heating-press technology.

Depending on the different kinds of mica raw materials, we can produce different mica sheets: Muscovite mica sheet, Phlogopite mica sheet, Synthetic mica sheet, and Calcined mica sheet. They can resist different temperatures.

Using stainless steel sheets as a separate material, we can produce a glossy mica sheet instead of glass fiber cloth.

There are also over-thick mica sheets, low-smoke mica sheets, and specially designed ones, such as stainless steel mesh inset mica sheets…

Mica Sheet Size

The popular mica sheet sizes are 600 x 1000 mm, 1200 x 1000 mm, 2000 x 1000 mm, and 2400 x 1000 mm. The mica sheet size depends on the size of the heating press machine. We have press machines that can process sheets of 2400*1000 mm, improving production efficiency, saving energy, and meeting customers’ demands for large-size products. The large size can also be cut into smaller sizes, such as 1200*1000 mm and 600*1000 mm, for convenient transportation.

We also have a heating press machine with a smaller size, 1200*1000mm, that can be used to process thick mica sheets, which require heating and pressing twice, similar to regular mica sheets. They can also process special mica sheets, such as stainless steel-woven mica sheets, synthetic mica sheets, and others.

Mica sheet is a star insulation material used in industrial applications. It can resist high temperatures and high voltages. The most popular mica sheet in the market is produced by the laminated process method, which is highly industrialized. We have eight sets of mica paper production lines, 10 sets of mica sheet glue machines, and four sets of heating press machines, which can produce 10,000 tons of Mica Sheet. Our mica sheet is certified by UL (E248686) and conforms to IEC371-3-3.

Flexible mica sheet

Flexible mica sheets can serve as the insulation layer for various electric appliances, equipment, furnaces, and electric vehicles.

Rigid Mica sheet

Rigid mica sheets comprise approximately 90% muscovite, phlogopite, or synthetic mica paper impregnated with high-temperature-resistant silicone resin.

In the photo, the gray face is a Muscovite Rigid Sheet, the middle brown color is a Phlogopite Rigid Sheet, and the white back is a Synthetic Rigid Sheet.

USED as supporting insulation for resisting wire, heating elements in electric toasters, hair dryers, irons, curlers, electric hot combs, strip heaters, baseboard heaters, and for gaskets and in other appliances and applications where excellent resistance to moisture and thermal, mechanical, and good electrical properties are required.

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.
• Heat and press the mica paper on the mica sheets.
• Cutting the mica sheets to size: 1000*600mm, 1000*1200mm, 1000*2400mm.
• Pack each 50kg mica sheet with PE film and a carton box, then fix each 1 ton with wooden pallets.

Mica Sheet Properties

1. Excellent heat resistance, even in open flame up to 1000℃.
2. Excellent electrical insulation.
3. High resistance to pressure.
4. Eco-friendly and non-toxic.
