Products Description
Industrial Sealing Solution Design with Flexible Graphite Materials
Engineered for critical industrial applications, our sealing solutions incorporate advanced flexible graphite materials including sheets, foils, papers, tapes, and strips. These materials are produced through a proprietary process: natural flake graphite undergoes chemical intercalation followed by thermal exfoliation at 1000°C+, forming vermicular structures with 0.003g/cm³ density. The binder-free expanded graphite is then calendared into rolls, offering:
- 99.8% purity
- Chemical resistance to acids/alkalis
- Gamma radiation tolerance (up to 10⁶ Gy)
- Thermal stability (-200°C to +650°C)
- 40% compression recovery
- Zero outgassing
- Leak-tight sealing
Industrial Sealing Applications:
- Pump & Valve Sealing Systems
- Flange Joints in Petrochemical Plants
- Heat Exchanger Gaskets
- Mechanical Seals for Rotating Equipment
- High-Temperature Insulation in Furnace Doors
Custom Design Capabilities:
- Laser-cut gaskets for complex geometries
- Metal-reinforced composites for high-pressure systems
- Die-stamped thick plates for flange sealing
- CNC-machined components for precision applications
