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.
