Product Description

Products Description
 

1mm Thick Flexible Graphite Gasket Sheet

 

Flexible graphite products include sheets, foils, papers, tapes, and strips. Manufactured through chemical intercalation and thermal exfoliation of natural flake graphite, these materials form vermicular structures with ~0.003g/cm³ density. The binder-free expanded graphite is rolled into coils, offering:

 

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

 

Ideal for low-pressure applications, these sheets can be laminated with metal for composite solutions.

 

Key Applications:

 

  1. Packing rings for valves/pumps
  2. Custom-shaped gaskets via die cutting
  3. High-temperature insulation in machinery

 

1mm Standard Specifications:

 

  • Roll Width: 1000mm / 1500mm
  • Coil Length: 30m / 50m / 80m
  • Sheet Size: 1000x1000mm / 1500x1500mm
  • Density: 0.8-1.25g/cm³
  • Material Grade: Pure graphite (no fillers)

 

Customization Options:

 

  • Thickness variations (0.15-5.0mm)
  • Composite reinforcements (stainless steel/copper)
  • Die-cut shapes for specialized applications
