Multi-Layer Composite Graphite Sheet Solutions
Our multi-layer composite graphite sheets are engineered using advanced lamination technology, combining flexible graphite materials with metal reinforcement layers. These composite solutions integrate the following components:
- Flexible graphite core layers (sheets/foils/papers)
- Stainless steel/nickel alloy reinforcement layers
- Optional adhesive-free bonding process
Manufacturing Process:
- Natural flake graphite undergoes chemical intercalation and high-temperature exfoliation to form vermicular structures (density ~0.003g/cm³)
- Expanded graphite is rolled into binder-free coils
- Composite sheets are produced via:
- Pressure lamination with metal meshes
- Vacuum-bonded multi-layer structures
- High-temperature sintering processes
Key Features:
- Layered construction enhances mechanical strength
- Maintains chemical resistance of pure graphite
- Radiation shielding capabilities
- Thermal stability (-200°C to +650°C)
- Compression recovery up to 85%
- Self-lubricating sealing performance
Application Scenarios:
- Multi-layered packing rings for rotating equipment
- Composite gaskets for flange sealing in petrochemical plants
- Heat exchanger seals requiring structural reinforcement
- Aerospace-grade thermal insulation panels
