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:
 
  1. Die-stamped packing rings for valves/pumps
  2. Laser-cut composite gaskets with metal inserts
  3. CNC-machined thick gaskets for high-temperature insulation
  4. 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
