Products Description

Premium Low Friction Graphite Sealing Solutions

Our low friction graphite sealing materials include flexible sheets, foils, papers, tapes, and strips. Manufactured through chemical intercalation and thermal exfoliation of natural graphite flakes, these products form vermicular structures with approximately 0.003g/cm³ density. The binder-free expanded graphite rolls feature:

  • Exceptional purity (99.8%+)
  • Chemical inertness
  • Radiation resistance
  • Extreme temperature stability (-200°C to +650°C)
  • Self-lubricating properties (μ=0.05-0.12)
  • Gas-tight sealing performance
  • High compression recovery

Ideal for low-pressure applications requiring minimal friction, these materials can be laminated with metal substrates for enhanced structural integrity.

Low Friction Applications:

  1. High-performance packing rings for rotating equipment
  2. Custom-shaped gaskets with reduced wear characteristics
  3. Graphite-metal composite seals for dynamic systems
  4. High-temperature insulation pads with lubricating properties

Customizable Specifications:

  • Roll Dimensions:
    • Width: 1000mm / 1500mm (custom widths available)
    • Length: 30m / 50m / 80m
  • Sheet Size: 1000x1000mm / 1500x1500mm
  • Thickness Range: 0.15-5.0mm
  • Density: 0.8-1.25g/cm³
  • Friction Coefficient: 0.05-0.12 (depending on formulation)

Engineered for low friction environments, our graphite sealing materials provide reliable performance in pumps, valves, and rotating machinery while maintaining dimensional stability.
