PAN-Based Graphite Felt

Max Graphite supplies PAN-based graphite felt to engineers, procurement teams, and furnace builders operating in high-temperature process industries, where insulation consistency is a direct process variable. We produce both soft and rigid PAN-based grades — long-fiber, fully graphitized — in blankets, boards, cylinders, and CNC-machined liner assemblies. Carbonization, graphitization, and purification are executed in-house, giving full control over grade, geometry, and ash content from precursor to finished part.

PAN-Based Graphite Felt: The Insulation Layer at the Heart of Your Furnace

PAN-based graphite felt is specified across solar PV crystal growth, diffusion and dopant furnaces, vacuum heat treatment, and high-temperature graphitization — applications where insulation performance directly drives energy efficiency, temperature uniformity, and cycle repeatability. PAN as a precursor delivers a mature cost-to-performance profile and predictable behavior across thousands of furnace cycles. Max Graphite produces both soft and rigid PAN-based grades, supplied as blankets, boards, cylinders, machined hot-zone components, and full furnace liner kits.

Soft and rigid forms from a single source: Conformable blanket and self-supporting board formats produced under one quality system — no split sourcing for hot-zone insulation.
Full long-fiber graphitization range: Carbonization and high-temperature graphitization deliver the thermal stability and fiber integrity required for repeated cycling in inert and vacuum atmospheres.
Purity controlled in-house: Dedicated purification furnaces reduce ash content and outgassing where contamination affects crystal quality, semiconductor process windows, or vacuum cleanliness.
Geometry from blanket to finished hot zone: Rolls, boards, cylinders, machined components, curved segments, and full liner kits supplied to specification.
Engineering support for qualification: Direct engagement with furnace builders and process engineers on grade, geometry, and surface treatment for new builds, retrofits, and qualified-vendor programs.
