CNC Machined Flexible Graphite Sheet 99.9% C Content With Custom Size

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:
  1. Laser-cut packing rings in any size
  2. Die-cut composite gaskets for specialized applications
  3. CNC-machined thick plates for high-temperature insulation
Standard & Custom Specifications:
  • Roll Width: 1000mm / 1500mm (custom widths available)
  • Coil Length: 30m / 50m / 80m (cut-to-length service)
  • Sheet Size: 1000x1000mm / 1500x1500mm (custom sizes up to 2000mm)
  • Thickness Range: 0.15-5.0mm
  • Density: 0.8-1.25g/cm³
