The following is about Mica Gasket related, I hope to help you better understand Mica Gasket.
Mica gasket l is an excellent alternative in these high temperature (to 1800 F) applications. Some of the basics on Mica are shown below. As a gasket material Mica can be very effective in sealing those high temp critical applications with out failing due to the presence of oxygen.
Withstands heat up to temperatures of 1850oF (1000oC). - Resists fire without burning. - Low heat conductivity.
Insulating strength better than 25 kV/mm. - Good resistance against arcing and arc erosion. - Permeability to microwaves.
