Product Description
Flexible Graphite Gasket Sheet Overview
Manufactured from natural graphite flakes through chemical treatment and high-temperature thermal expansion, our flexible graphite products offer exceptional performance in demanding industrial applications. The material undergoes specialized processing to create exfoliated graphite particles that are compressed into rolls and sheets without binders or fillers.
Key Material Properties
- Temperature Resistance: Operates from -200°C to +3000°C
- Radiation & Corrosion Resistance: Excellent performance in harsh environments
- Mechanical Performance: Superior compression resilience and self-lubrication
- Impermeability: Effective low-pressure sealing capabilities
- Hybrid Compatibility: Can be combined with metal sheets for reinforced composite plates
