Mica Gaskets

Mica or micanite gasket material is exceptional in it resistance to high heat. At temperatures over 500 C the ideal sealing material of flexible graphite cannot be used. Flexible graphite will coke at those elevated temperatures when oxygen is present, where mica gasket material will not (500C - 1100 C).

Mica gasket material is an excellent alternative in these high temperatures (to 1100 C) 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 without failing due to the presence of oxygen.

Mica is a mineral, which offers a wide range of exceptional properties. You may find that some of the properties of mica could improve the different products in your range.

Mica which comes in the form of flakes is completely harmless and presents very high thermal and mechanical performances, allowing it to successfully replace asbestos gasket material in many applications.

Applications include but not limited to:

• Supports for heating resistors (i.e. convectors).
• Thermal insulation in circuit breakers and between electronic components
• In large thickness, as thermal insulators for industries with large stress such as iron and steelworks, chemical, glass and petrochemical industries
• Mechanical support and electrical insulator in high voltage cabins
• Replacements for asbestos panels in forging machines and hydraulic presses
• Automotive (exhaust manifolds)
• Fuel cells; gas turbines & turbo generators.
• It can also be used as filler for spiral wound gaskets or as a material for cam profile gaskets.
