Flexible Graphite Material (Expanded Graphite Sheet)
Composed of natural graphite flakes processed through chemical treatment and thermal expansion, flexible graphite material—also referred to as expanded graphite foil or graphite tape—is engineered by exposing raw graphite to elevated temperatures. This process creates exfoliated graphite structures with an ultralow bulk density of approximately 3 kg/m³. These expanded graphite particles are subsequently compressed into rolls or sheets without binders or additives, ensuring exceptional purity and performance characteristics.
Key Properties
Corrosion & Radiation Resistance: Suitable for harsh chemical and nuclear environments.
Extreme Temperature Tolerance: Stable performance across a broad thermal range (-200°C to +3000°C).
Self-Lubrication & Sealing Efficiency: Inherent lubricity and impermeability for reliable low-pressure sealing.
Compressive Resilience: Maintains structural integrity under repeated compression cycles.
Applications
Sealing Solutions: Serves as a primary material for manufacturing graphite packing rings and composite gaskets.
Composite Materials: Combined with metal sheets to create multi-layered sealing plates, customizable into complex gasket geometries.
Direct Industrial Use: Processed into thick sheets for crafting low-pressure seals or high-temperature insulation pads in industrial equipment.
Customization: Non-standard sizes, densities, or hybrid material configurations available upon request.
