Products Description
 

Graphite Gasket Technical Consultation
Your One-Stop Source for Custom Sealing Solutions
 
Flexible graphite materials, including sheets, foils, papers, tapes, and strips, are engineered through advanced chemical intercalation and thermal exfoliation processes. Natural graphite flakes undergo controlled expansion at high temperatures to form worm-like structures with a density of ~0.003g/cm³. These expanded graphite rolls are binder-free, ensuring:
 
  • 99.5%+ purity
  • Chemical resistance
  • Radiation tolerance
  • Thermal stability (-200°C to +650°C)
  • Compression recovery
  • Self-lubricating properties
  • Gas-tight sealing
 
Graphite Gasket Applications
Our technical experts recommend these materials for:
 
  1. Valve and pump packing rings
  2. Custom-engineered flange gaskets
  3. High-temperature insulation systems
  4. Composite seals with metal reinforcement
