Rigid Graphite Felt Boards and Cylinders
Max Graphite supplies rigid graphite felt boards and cylinders to engineers and procurement teams in heat treatment and broader high-temperature process industries, where insulation pack integrity is a direct process variable. We carry the full PAN- and rayon-based rigid felt grade range, machine boards and cylinders to drawing, and apply graphite foil, C/C cloth, and pyrolytic carbon coatings for edge and erosion protection. Single-source coverage across grade, geometry, and coating lets buyers specify and qualify without splitting supply.
Vacuum Furnace Insulation Where Pack Stability Defines the Process
Rigid graphite felt boards and cylinders are specified into vacuum and inert-gas furnace insulation packs across heat treatment, sintering, brazing, vacuum metallurgy, mono-Si and SiC crystal growth, MOCVD and CVD systems, and powder metallurgy. Pack stability — dimensional, thermal, and chemical — directly governs cycle consistency, yield, and replacement cadence. Max Graphite covers the full rigid felt insulation range from one qualified line.
- Boards, cylinders, and machined shapes to drawing. Flat panels, cylinders, segmented sections, and 3D geometries from one integrated process.
- Full PAN and rayon rigid felt grade coverage. Buyers specify against insulation, mechanical, or cost requirements without changing supplier.
- Surface coating and edge protection. Graphite foil, C/C cloth, and pyrolytic carbon coatings for oxidizing or erosive operating windows.
- Stock and custom production cadence. Standards held for short lead times; machined shapes scheduled to project timelines.
- In-house engineering and qualification. Material selection, geometry review, and audit documentation handled by our team.
Why Max Graphite
- One qualified vendor across grade, geometry, and coating. The full insulation pack consolidates into a single supplier of record.
- Continuity of supply across OEM build and aftermarket. Production is sized for build schedules and replacement cycles in parallel.
- A partnership built around procurement. Lead-time visibility, documentation, and engineering input are built into the relationship.
- For full grade designations, dimensional ranges, and coating specifications, see the Graphite Rigid Felt material datasheet.
