PAN carbon felt product is manufactured from polyacrylonitrile precursor and it is pre-fired at 2192 ºF (1200 ºC) in order to complete the carbonization of the starting precursor material.  This is a soft felt material with good flexibility and compressibility.  It is easy to cut to different sizes using different cutting tools such a die cutter, a pair of scissor, or a heavy duty office paper trimmer.  PAN based carbon felt materials are usually used for redox flow batteries and microbial fuel cells as the electrode or current collector, insulating layer for furnaces, or as heat shields and heat sinks and various other relevant applications. Following redox flow battery image is courtesy of Alejandro Clemente et al. and furnace thermal insulation is courtesy of Vac Aero International to show exemplary applications that can use carbon felt products.

This product has a thickness tolerance of 12.7 mm +/- 2 mm and interested parties should procure a small sample first for their intended application prior to placing an order for bulk volume.
