ZOLTEK PXFT carbonized felts are produced from 100% ZOLTEK OX felts; that are continuously carbonized and supplied in roll form. ZOLTEK PXFT carbon felts can be used in many applications, including: stationary energy storage batteries, high temperature furnace linings, acid gas mist eliminators and as a carbon composite materials. Customers can apply their own post treatments and the felt is easy to process into customer specific designs.
