High Pressure Dynamic Sealing Graphite Gasket Sheet Smooth Finished Industrial Grade

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

1. Dynamic Sealing Systems: Primary material for rotating shaft packing rings in pumps/valves

2. Composite Gasket Fabrication: Metal-reinforced multilayer sheets die-cut into custom flange gaskets

3. Direct-Form Components: Thickened plates (3-5mm) processed into low-pressure seals or thermal barriers

Standard Specifications

Note: Custom dimensional configurations and material hybrids available for OEM requirements.

This engineered material series addresses critical sealing challenges across energy generation, process industries, and advanced manufacturing sectors through its unique combination of thermal conductivity (5-150 W/m·K) and structural adaptability.
