Sand Resistant Flexible Graphite Sheet 99.9% For Sealing Gaskets

Products Description

Sand-Resistant Flexible Graphite Sheet

Flexible graphite products include sheets, foils, papers, tapes, and strips. These materials are produced by chemically intercalating natural graphite flakes followed by high-temperature exfoliation, creating vermicular structures with ~0.003g/cm³ density. The binder-free expanded graphite is calendared into rolls, offering:

  • 99%+ purity
  • Chemical inertness
  • Radiation resistance
  • Thermal stability (-200°C to +650°C)
  • Compression recovery
  • Self-lubricating properties
  • Gas-tight sealing
  • Enhanced abrasion resistance through surface treatment

Ideal for harsh environments, these sheets feature specialized coatings to resist sand erosion while maintaining sealing performance. Composite options with metal reinforcements are available.

Specialized Applications:

  1. Packing rings for desert machinery
  2. Sealing gaskets for dusty industrial equipment
  3. High-temperature insulation in abrasive conditions
  4. Composite seals for pumps/valves in sandy environments

Standard & Custom Specifications:

  • Roll Width: 1000mm / 1500mm (custom up to 2000mm)
  • Coil Length: 30m / 50m / 80m (cut-to-length service)
