Product Description

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:

Valve and pump packing rings
Custom-engineered flange gaskets
High-temperature insulation systems
Composite seals with metal reinforcement
