Product Description
Industrial Graphite Gasket Material Overview
Flexible graphite materials including sheets, foils, papers, tapes, and strips are manufactured through a specialized process. Natural graphite flakes undergo chemical treatment and high-temperature heating to create graphite worms, which are then rolled into flexible graphite coils with exceptional sealing properties.
Key Material Properties
High-purity flexible graphite coils contain no binders or fillers, providing superior performance characteristics for industrial sealing applications.
- Excellent corrosion resistance for harsh chemical environments
- Superior radioactivity resistance for specialized applications
- Wide temperature range from -200°C to 600°C
- Good compression resilience and self-lubrication properties
- Impermeable sealing capabilities for low-pressure components
Product Applications
- Manufacturing graphite packing rings for industrial equipment
- Combining with metal sheets to create graphite composite plates
- Producing various sealing gaskets in diverse shapes and sizes
- Direct use as thick plates for low-pressure gaskets or high-temperature insulation pads
