Products Description

50MPa Compressive Strength Graphite Gasket

Flexible graphite products include sheets, foils, papers, tapes, and strips. These materials are manufactured by chemically intercalating natural flake graphite followed by high-temperature exfoliation, resulting in vermicular graphite structures with approximately 0.003g/cm³ density. The binder-free expanded graphite is calendared into rolls, offering:

99%+ purity
Chemical inertness
Radiation resistance
Thermal stability (-200°C to +650°C)
49.50MPa compressive strength
High compression recovery
Self-lubricating properties
Gas-tight sealing performance

These features make them ideal for critical low-pressure sealing applications. Composite options with metal reinforcements are available.

Industrial Applications:

High-strength packing rings for pumps/valves
Custom-shaped gaskets via laser cutting
Thick insulation pads for high-temperature environments
Sealing solutions for chemical processing equipment
