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:

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

Product Applications:

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