Online Custom Graphite Gasket Service
Products Description
Instant Custom Graphite Gasket Solutions
Our online platform offers tailor-made graphite-based sealing solutions including: flexible sheets, foils, papers, tapes, and strips. These materials are produced by intercalating natural graphite flakes with chemical agents, followed by thermal expansion to create worm-like structures (density ≈0.003g/cm³). The binder-free expanded graphite is then rolled into coils, delivering:
- 99%+ purity
- Corrosion/radiation resistance
- Extreme temperature stability (-200°C to +650°C)
- Compression recovery up to 40%
- Self-lubricating performance
- Gas-tight sealing
Online Customization Features:
- Real-time design quoting system
- CAD file upload for precision cutting
- Material selection wizard (pure/graphite-metal composite)
- Thickness calculator (0.15-5.0mm)
Industrial Applications:
- Pump/valve sealing systems
- High-temperature insulation components
- Custom-shaped gaskets for energy sector
- Automotive engine seals
Service Advantages:
- 24/7 online ordering portal
- Rapid prototyping (48-hour turnaround)
- Free design optimization
- Bulk pricing discounts
