Product core

Pure Graphite Packing Tape is crafted from high-purity natural flake graphite through chemical intercalation and high-temperature expansion processes. Its core advantages include a pure, carbon-based structure with zero impurities, exceptional heat resistance (-200°C to 800°C), chemical inertness (resistant to pH 0-14 media), and tight sealing properties. Utilizing precision CNC cutting technology, the Pure Graphite Packing Tape features a smooth surface without burrs, combined with compressibility and resilience. It self-forms without requiring any adhesive.

Product Features

1.100% purity: No adhesives or fillers to ensure chemical inertness, acid and alkali resistance and organic solvent corrosion

2.Ultra high thermal conductivity: The surface thermal conductivity coefficient is 500-1500 W/m·K, which meets the heat dissipation requirements of high power devices

3.Wide temperature tolerance: Maintains stable performance in -200℃ to 3000℃ (inert environment) and adapts to drastic thermal cycling

4.Excellent compression rebound: Maintain sealing integrity under pressure, low creep relaxation to ensure long-term reliability

5.Lightweight flexibility: Can be easily cut, stamped or wrapped around complex geometries, supporting customized thermal management/emagnetic shielding solutions

6.Conductive properties: In-plane resistivity ≤ 0.001 Ω·cm, suitable for grounding or static dissipation

7.Process characteristics: expansion ratio>350 times, worm-like porous structure is formed, strong adsorption capacity, can absorb oil pollution of its own weight 30 times;

Application Area

1.Industrial sealing: static and dynamic sealing of petrochemical pipelines, reaction vessels, valves and pump bodies, replacing traditional asbestos/fluoroplastics to prevent leakage of high temperature and high pressure media;

2.Electronic heat dissipation: the thermal pad of smart phones, LED lamps and other devices can evenly disperse hot spots and improve the service life of components;

3.Fire retardation: fire door sealing strip, cable sealing material, expand instantly in case of fire to form an insulation layer, blocking the spread of smoke and flame;

4.Aerospace: Thermal interface material (TIM) for satellites and avionics

5.Electromagnetic shielding: conductive shielding tape on the shell of electronic equipment to suppress radio frequency interference

6.Special scenarios: cryogenic sealing of liquid hydrogen storage tanks and protection of equipment in highly corrosive environments (such as concentrated hydrochloric acid and strong alkali).

The Pure Graphite Packing Tape delivers exceptional performance across these diverse applications while maintaining its unique material properties.
