The thin mica sheets are mainly used to pounched to mica gaskets, that can used as heating wire holder in machines, such as electric hair dryer, microwave oven, and so on. The thick rigid mica sheet will CNC process to mica parts. That has large strength, and can resist both high temperature and high voltage.

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

And depending on the different kind mica raw material, we can produce different kind mica sheets: Muscovite mica sheet, Phlogopite mica sheet, Synthetic mica sheet, and Calcined mica sheet.They can resist different temperatures.

When using the stainless steel sheet as a separate material, instead of the glass fiber cloth, we can make the glossy mica sheet.

There are also over-thick mica sheet, low smoke mica sheet, stainless steel mesh inset mica sheet…

Mica Sheet Size

The popular mica sheet size is 600*1000mm, 1200*1000mm, 2000*1000mm, 2400*1000mm. The mica sheet size depends on the heating press machine size. We have the press machines that can process the size 2400*1000mm, which can develop the production efficiency, save energy, and meet customer large size demand. The large size can also cut to small size 1200*1000mm and 600*1000mm.

We also have the heating press machine with a smaller size 1200*1000mm, that can be used to process the thick mica sheet, which need to heating press for double-time than normal mica sheet. And that can also used to process the special mica sheet, such as stainless steel woven mica sheet, synthetic mica sheet, and so on

The mica sheet is star insulation material for industrial. It can resist high temperature and high voltage. And in the market, the most popular is the mica sheet produced by the laminated process method, it is with a high industrialized degree. We have 8 sets mica paper production line, 10 sets mica sheet glue machine and 4 sets heating press machine. That can produce 10000Tons Mica Sheet. Our mica sheet is certified by UL (E248686) and in conformity with IEC371-3-3.

How do Mica Sheets work?

Mica sheets work as the high-performance thermal and electrical insulation in a broad range of industries such as:

  • USED as supporting insulation for resisting wire,  heating elements in the electric toaster, hairdryer…
  • heating elements for electrical & thermal mechanical equipment
  • construction of induction, arc or high-frequency furnaces
  • high voltage applications
  • high thermal applications
  • industrial sealing & gasket industries (e.g. oil & gas distribution)
