PAN-Based Graphite Felt vs Rayon-Based Graphite Felt
PAN-based and rayon-based graphite felt are common material options in graphite felt purchasing.
Grade Mapping
In RuiGong soft graphite felt specifications, RG-SP and RG-HP are PAN-based options, while RG-SV and RG-HV are rayon-based options. RG-HP and RG-HV are listed as high-purity grades. This mapping helps buyers narrow the technical table before discussing dimensions and application details.
What to Compare
Buyers should compare thickness, density, width, ash, thermal conductivity and treatment temperature. These values are shown on the soft graphite felt page.
Application Review
The best choice depends on application, operating atmosphere and purity requirement. Send the application and specification target before quotation.
Practical Buying Checklist
- Confirm whether PAN-based or rayon-based felt is preferred.
- Compare standard and high-purity grade ash values.
- Review thickness, density, width and thermal conductivity.
- State application, atmosphere, dimensions and quantity.
What to Discuss With a Supplier
Ask for the exact grade designation in the quotation. If purity is important, state the target or inspection requirement instead of using the word high purity without a measurable acceptance criterion.
Verify Before a Volume Order
Use the technical table for initial comparison, then confirm the ordered grade and dimensions on the purchase document. A sample can help verify handling, fit and compatibility with the intended process.
