Product Description

Products Description
 

his advanced material category encompasses oxidation-resistant graphite sheets, foils, tapes, and strips, engineered to withstand oxidative degradation while maintaining flexibility.

Manufacturing Innovation
Natural graphite undergoes acid intercalation followed by rapid thermal expansion (900-1200°C), creating vermiform expanded graphite with a porous density of 0.0032g/cm³. The oxidation-resistant variant incorporates proprietary antioxidant treatments during calendaring, eliminating binder dependency while enhancing air stability.

Performance Advantages

  • Oxidative Stability: Withstands continuous operation at 450°C in oxygen-rich environments (vs. 300°C standard grades)

  • Multi-Environmental Resistance:

    • Chemical: Resists acidic/alkaline corrosion (pH 0-14)

    • Thermal: Maintains integrity from -240°C to +2800°C (intermittent)

    • Mechanical: 90% compression recovery after 10,000 cycles

  • Hybrid Compatibility: Bonds with SUS304/Inconel sheets via diffusion welding for reinforced composites

Industrial Implementation

  1. High-Temperature Sealing: Oxidation-resistant packing rings for steelmaking furnace doors & gas turbine flanges

  2. Aerospace Thermal Management: Lightweight gaskets in rocket engine fuel lines and re-entry vehicle insulation

  3. Automotive Exhaust Systems: Custom-shaped composite gaskets for turbocharger housings and EGR valves

  4. Semiconductor Manufacturing: Ultra-clean seals in CVD chamber assemblies requiring oxidation control
