Products Description

3mm Thick Graphite Sealing Sheets

Flexible graphite materials include sheets, foils, papers, tapes, and strips. Manufactured from natural flake graphite through chemical intercalation and high-temperature exfoliation, these materials form worm-like structures with approximately 0.003g/cm³ density. The binder-free expanded graphite is calendared into rolls, offering:

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

3mm Thick Sheet Features:

  • Ideal for high-temperature insulation applications
  • Provides enhanced sealing performance in low-pressure systems
  • Available in pure graphite or metal-reinforced composites

Product Applications:

  1. Custom packing rings for pumps and valves
  2. Die-cut gaskets for specialized equipment
  3. Thick insulation pads for high-temperature environments

Standard Specifications:

  • Sheet Thickness: 3.0mm (other thicknesses: 1.0-5.0mm)
  • Sheet Size: 1000x1000mm / 1500x1500mm
