What are mica gaskets

Mica gaskets are industrial sealing components manufactured from mica-based materials and designed for applications involving high temperatures. They are commonly used as heat resistant gaskets where conventional rubber or fibre materials are not suitable.

Mica sealing gaskets are valued for their thermal stability, non-combustible properties and ability to maintain sealing integrity under extreme heat conditions.

When do you need mica gaskets

Mica gaskets are used when sealing applications involve elevated temperatures, hot gases or thermal cycling. They are typically selected for static sealing situations where temperature resistance is more important than elasticity.

These high temperature gaskets are often applied in systems where fire safety, thermal insulation or resistance to heat-induced material degradation is required.

Applications of mica gaskets

Mica gaskets are applied in furnaces, boilers, exhaust systems, heat exchangers and high-temperature flange connections. They are widely used in power generation, petrochemical processing, metallurgy and heavy industrial manufacturing.

Industrial mica gaskets can be supplied in standard gasket formats and are also suitable for applications where consistent performance is required under prolonged heat exposure.

Mica gaskets specifications

Material type: Mica-based gasket (phlogopite or muscovite)
Operating pressure: suitable for medium to high pressure systems
Temperature range: up to +900 °C (depending on mica type and reinforcement)
Mechanical stability: excellent at elevated temperatures
Sealing performance: reliable under extreme thermal conditions

Mica gaskets are designed for high-temperature sealing applications where conventional fibre, PTFE or graphite gaskets are no longer suitable. They are commonly used in exhaust systems, boilers and industrial flanges exposed to extreme heat.

Custom production

In addition to standard Mica gaskets, we can CNC cut custom shapes and dimensions to your drawing. Suitable for prototypes, small series and repeat production.
