Product Description

Products Description

Custom-Sized Flexible Graphite Gaskets

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

99%+ purity
Chemical inertness
Radiation tolerance
Thermal stability (-200°C to +650°C)
Compression recovery
Self-lubricating properties
Gas-tight sealing

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

Customization Capabilities:

Laser-cut packing rings in any size
Die-cut composite gaskets for specialized applications
CNC-machined thick plates for high-temperature insulation
