Graphite Gaskets
Flexible graphite is a versatile, organic, sealing material frequently used in high-performance gasket applications, particularly where high temperatures, pressures, and corrosive environments are present. It's made from natural graphite flakes that are expanded and then compacted into a sheet form.
Advantages of flexible graphite gaskets
Excellent Sealing: Its compressibility allows it to conform to uneven flange surfaces and create a tight seal, even under varying pressures and thermal conditions.
Thermal Stability: Flexible graphite maintains its structural integrity and sealing effectiveness across a wide range of temperatures, from -200°C (-400°F) to 3,000°C (5,400°F) in a non-oxidizing atmosphere.
Chemical Resistance: It is resistant to a wide range of corrosive chemicals, acids, and solvents, making it suitable for use in harsh chemical processing environments.
Low Permeability: Flexible graphite has low gas and liquid permeability, making it an effective sealing material for high-pressure and high-temperature applications.
Durability and Resilience: Unlike polymer-based gasket materials, it maintains its characteristics across a wide range of temperatures, resists stress relaxation, and offers a good recovery rate, ensuring a long lifespan.
Non-Hazardous: It's considered a non-hazardous material, complying with regulations like RoHS and REACH, and is safe for handlers.
Non-Stick Properties: Its naturally slippery nature facilitates easier removal and replacement of gaskets.
