Flexible Purified Graphite Felt – 5mm Roll for Hot-Zone Insulation

Product Summary

This 5mm semiconductor soft felt provides robust thermal insulation for demanding high-temperature processes. With a carbon content of ≥99.99%, tensile strength of 0.12–0.25 MPa, and moisture absorption below 1.0%, it is an excellent choice for flexible hot-zone wrapping in silicon and silicon carbide crystal growth furnaces. The increased thickness offers enhanced thermal resistance while maintaining flexibility.

Key Selling Points

• High Purity: ≥99.99% carbon content reduces contamination risk in semiconductor processes.
• Enhanced Thickness: 5mm (±10%) offers greater thermal insulation capability for extreme heat zones.
• Low Moisture Absorption: <1.0% ensures stable performance and prevents outgassing.
• Mechanical Strength: Tensile strength of 0.12–0.25 MPa for reliable handling and installation.
• Application Flexibility: Easily tailored around heater boundaries in single crystal furnaces.
