Products Description

Flexible Graphite Products Overview

Material Composition & Production
Derived from natural graphite flakes, flexible graphite products—including sheets, foil, tape, and strips—undergo a specialized manufacturing process. Raw graphite is chemically treated and thermally expanded at high temperatures, forming exfoliated "graphite worms" with a bulk density of ~0.003 g/cm³. These expanded particles are then compressed into rolls or sheets without binders or fillers, ensuring high purity and enhanced performance.

Key Characteristics

  • Environmental Resistance: Excellent corrosion, radiation, and extreme temperature tolerance (-200°C to +3000°C).

  • Mechanical Properties: Superior compression resilience, self-lubrication, and impermeability for effective low-pressure sealing.

  • Hybrid Compatibility: Combines with metal sheets to create reinforced graphite-metal composite plates.

Primary Applications

  1. Sealing Components: Used as core material for graphite packing rings and custom-shaped gaskets.

  2. Composite Fabrication: Bonded with metal layers to produce multi-functional sealing sheets, cut into complex geometries.

  3. Direct Industrial Use: Processed into thick plates for manufacturing low-pressure seals or high-temperature insulation pads.

Standard Specifications

  • Dimensions:

    • Width: 1000mm / 1500mm

    • Coil Length: 30m, 50m, or 80m

    • Thickness: 0.15–1.0mm (coils) / 1.0–5.0mm (plates)

  • Density Range: 0.8–1.25 g/cm³

  • Custom Options: Tailored sizes, densities, or hybrid configurations available for specialized requirements.

Ideal for aerospace, energy systems, and industrial machinery, this material delivers reliability in demanding environments while adhering to strict purity and safety standards.
