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.
