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:

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