PAN-Based Carbon Felt

Product

Polyacrylonitrile-based (PAN) carbon felt is a fluffy and porous carbon material made by using PAN precursor as the precursor, through needling process, and then carbonization at 1200℃. It perfectly inherits the inherent excellent properties of carbon fiber, including outstanding high-temperature resistance, extremely high chemical inertness, excellent electrical and thermal conductivity, as well as a low coefficient of thermal expansion. It can withstand high temperatures up to 1500℃ for a long time. Thermal conductivity ≤0.25W/m·k.
