Product Description

Products Description

Precision-Stamped Flexible Graphite Gaskets

Stamped flexible graphite gaskets belong to the flexible graphite material family, including sheets, foils, papers, tapes, and strips. These gaskets are manufactured by chemically treating natural graphite flakes and subjecting them to high-temperature exfoliation, forming worm-like structures with approximately 0.003g/cm³ density. The binder-free expanded graphite is then rolled into coils, offering:

99.5% purity
Chemical resistance
Radiation tolerance
Extreme temperature stability (-200°C to +650°C)
Compression recovery
Self-lubricating properties
Gas-tight sealing performance

Ideal for low-pressure systems, these stamped flexible graphite gaskets can be combined with metal substrates to create composite solutions.

Manufacturing & Applications:

Die-stamped packing rings for valves/pumps
Laser-cut composite gaskets with metal inserts
CNC-machined thick gaskets for high-temperature insulation
Pre-cut stamped flexible graphite gaskets for quick installation

Customization Options:

Available in 0.15-5.0mm thickness
Standard sizes: 1000x1000mm / 1500x1500mm sheets
Custom stamped shapes/sizes up to 2000mm
Density: 0.8-1.25g/cm³
Composite grades: Graphite-metal laminates

Production Process:
Natural flake graphite → Chemical intercalation → High-temperature expansion → Calendaring → Die-stamping → Quality inspection
