Product Description

Products Description

Precision Laser-Cut Graphite Sealing Sheets
Customizable Solutions for Industrial Sealing Applications

Flexible graphite materials include sheets, foils, papers, tapes, and strips. These products are manufactured through chemical intercalation of natural graphite flakes followed by high-temperature exfoliation, creating vermicular graphite structures with 0.003g/cm³ density. The binder-free expanded graphite is rolled into coils, offering:

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

Laser Cutting Advantages:
Our state-of-the-art laser cutting technology ensures:

Micron-level precision for intricate gasket shapes
Burr-free edges for optimal sealing performance
Fast turnaround for custom-sized orders
Compatibility with all graphite sheet thicknesses

Product Applications:

Laser-cut packing rings for pumps and valves
Custom-shaped sealing gaskets from composite graphite-metal sheets
High-temperature insulation pads cut via laser from thick graphite plates
