Products Description
Global Logistics Graphite Sealing Material
Graphite sealing materials include flexible sheets, foils, papers, tapes, and strips. These logistics-grade sealants are produced by chemically treating natural graphite flakes and subjecting them to high-temperature exfoliation, forming vermicular graphite structures with approximately 0.003g/cm³ density. The binder-free expanded graphite is calendared into rolls, offering:
- 99%+ purity for contamination-free logistics
- Chemical resistance for corrosive environments
- Extreme temperature stability (-200°C to +650°C) for global shipping conditions
- Compression resilience for long-term sealing performance
- Self-lubricating properties for easy installation
- Gas-tightness for pressure-sensitive logistics applications
These features make our graphite sealing solutions ideal for international logistics equipment, including:
Key Applications in Global Logistics:
- Container sealing systems
- Pipeline gaskets for cross-border transportation
- High-temperature insulation for logistics machinery
- Valve packing rings in international shipping equipment
Logistics-Optimized Specifications:
- Roll Widths: 1000mm / 1500mm (standard for global container dimensions)
- Coil Lengths: 30m / 50m / 80m (economical for bulk logistics)
