Products Description

Low Cost Flexible Graphite Gasket
Flexible graphite materials encompass a range of products including rolls, foils, papers, tapes, and strips. These materials are manufactured by subjecting natural flake graphite to chemical intercalation followed by high-temperature exfoliation, resulting in worm-like graphite structures with a density of approximately 0.003g/cm³. The expanded graphite is then calendared into binder-free rolls, offering exceptional purity. Key properties include:
  • High chemical resistance
  • Radiation tolerance
  • Extreme temperature stability (-200°C to +650°C)
  • Superior compression recovery
  • Self-lubricating characteristics
  • Gas/tightness performance
These attributes make it ideal for low-pressure sealing applications. Composite materials can be produced by laminating with metal substrates.
Application Fields:
  1. Core material for packing rings
  2. Composite sheets with metal layers for custom-shaped gaskets
  3. Thick sheets for low-pressure seals or high-temperature insulation pads
