Oxi-PAN 6A
SERIAL PRODUCTION
Standard grade for graphite-electrode programs.
Status: in current production programs
HANBOO SOLUTION / OXI-PAN CARBON FELT
Carbon felt for
graphite electrodes
Oxi-PAN is polyacrylonitrile fiber, thermally stabilized and needle-punched into a dense carbon-black felt. It goes into the graphite-electrode processes behind secondary batteries and ESS — in serial production today, with the heat resistance of a material that chars instead of melting.

Applications
Where Oxi-PAN earns its keep
- Secondary-battery & ESS graphite electrodes
Carbonized-fiber felt for graphite-electrode production — our core Oxi-PAN application, in serial production and protected by patent 10-2135198. - High-temperature process duty
A secondary strength: Oxi-PAN chars instead of melting, so it also serves furnace and process environments where organic felts fail. - Flame-barrier layers
Char-forming protective layers in composite constructions. - Precursor applications
Oxidized-PAN as a stage toward carbon-fiber materials — development with partners.
From precursor fiber to electrode process
- PAN precursor fiber
- Thermal stabilization (oxidation)
- Fiber opening & carding
- Needle punching to grade weight — 6A · 6B · 6C
- Inspection, winding & roll packing
- Customer electrode process — carbonization · graphitization
