Product Description
Precision Laser-Cut Graphite Sealing Sheets
Customizable solutions for industrial sealing applications with flexible graphite materials including sheets, foils, papers, tapes, and strips.
Material Properties
Manufactured through chemical intercalation of natural graphite flakes followed by high-temperature exfoliation, creating vermicular graphite structures with 0.003g/cm³ density. Binder-free expanded graphite rolled into coils offers:
- 99%+ purity with excellent chemical inertness
- Radiation resistance and thermal stability from -200°C to +650°C
- High compression recovery and self-lubricating properties
- Superior gas-tight sealing performance
Laser Cutting Advantages
State-of-the-art laser cutting technology ensures optimal performance:
- 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
