Product Description

Products Description

3mm Thick Graphite Sealing Sheets

Flexible graphite materials include sheets, foils, papers, tapes, and strips. Manufactured from natural flake graphite through chemical intercalation and high-temperature exfoliation, these materials form worm-like structures with approximately 0.003g/cm³ density. The binder-free expanded graphite is calendared into rolls, offering:

99%+ purity
Chemical resistance
Radiation tolerance
Thermal stability (-200°C to +650°C)
Compression recovery
Self-lubricating properties
Gas-tight sealing

3mm Thick Sheet Features:

Ideal for high-temperature insulation applications
Provides enhanced sealing performance in low-pressure systems
Available in pure graphite or metal-reinforced composites

Product Applications:

Custom packing rings for pumps and valves
Die-cut gaskets for specialized equipment
Thick insulation pads for high-temperature environments
