Product Description

Products Description

1.8g/cm³ High-Density Flexible Graphite Sheets

Flexible graphite products include sheets, foils, papers, tapes, and strips. These materials are manufactured through chemical intercalation of natural flake graphite followed by high-temperature exfoliation, forming vermicular structures with 0.003g/cm³ density. The expanded graphite is calendared into binder-free rolls, then processed to achieve:

1.8g/cm³ controlled density
99%+ purity
Chemical inertness
Radiation resistance
Thermal stability (-200°C to +650°C)
Compression recovery
Self-lubricating properties
Gas-tight sealing

These features make high-density sheets ideal for demanding sealing applications. Composite options with metal reinforcement available.

Key Applications:

High-pressure packing rings
Custom-shaped gaskets for industrial machinery
Thick insulation pads for high-temperature systems
Sealing components for chemical processing equipment
