High Pressure Industrial Graphite Sealing Gasket

Products Description

Product Range
Flexible graphite solutions encompass sheets, foil, tape, strips, and paper-form variants, collectively known as expanded graphite materials.

Manufacturing Process
Natural graphite flakes undergo chemical intercalation followed by rapid thermal expansion at 800-1000°C, creating exfoliated graphite particles with a bulk density of ~3 kg/m³. These expanded particles are mechanically compacted into continuous coils or sheet formats without adhesives or additives, ensuring 99%+ purity.

Key Advantages

Environmental Stability: Resists chemical degradation, ionizing radiation, and thermal extremes (-200°C to +3000°C)
Mechanical Performance: Maintains 85%+ compression recovery rate after cyclic loading
Interface Compatibility: Combines with stainless steel/copper sheets via lamination for hybrid structural materials

Industrial Applications

Dynamic Sealing Systems: Primary material for rotating shaft packing rings in pumps/valves
Composite Gasket Fabrication: Metal-reinforced multilayer sheets die-cut into custom flange gaskets
Direct-Form Components: Thickened plates (3-5mm) processed into low-pressure seals or thermal barriers
