Product Description
Advanced Multi-Layer Composite Graphite Sheet Technology
Our engineered multi-layer composite graphite sheets combine flexible graphite materials with metal reinforcement layers using advanced lamination technology. These high-performance solutions deliver exceptional mechanical strength while maintaining the superior properties of pure graphite.
Manufacturing Process & Construction
- Natural flake graphite undergoes chemical intercalation and high-temperature exfoliation
- Expanded graphite rolled into binder-free coils with density ~0.003g/cm³
- Composite sheets produced via pressure lamination, vacuum-bonded structures, and high-temperature sintering
- Layer configurations from 2-ply (graphite + metal) to 5-ply structures
Key Performance Features
- Enhanced mechanical strength through layered construction
- Maintains chemical resistance of pure graphite
- Radiation shielding capabilities
- Thermal stability from -200°C to +650°C
- Compression recovery up to 85%
- Self-lubricating sealing performance
