flat carbon felt
Flat carbon felt : PAN-based flat panel felt for materials by high temperature carbon fiber felt is widely used in a variety of high-temperature vacuum furnace insulation materials, hot gas or liquid and molten metal filter, fuel cells, porous electrodes, catalyst supports, corrosion-resistant container composite lining, also do the carbon / carbon composites reinforced materials. 90% of the carbon felt as a gap, insulation material performance is excellent, stable in high temperature environment of a vacuum or inert gas. Has a light and soft, and specific heat capacity, thermal insulation, convenience of operation.
