Polyacrylonitrile based ink felt has greater strength and oxidation resistance than viscose based ink felt, but it has poor flexibility, large bulk density and good thermal insulation performance. In addition to the high purity, high temperature resistance, corrosion resistance, non melting and other characteristics of block graphite, they also have the advantages of elasticity, free folding, tailoring and can be stitched with graphite yarn. Graphite felt is mainly used as insulation material for single crystal silicon smelting furnace. In the chemical industry, it can be used as a filter material for high-purity corrosive chemical reagents. The graphite felt can be used at a temperature of about 3000 ° C in a non oxidizing atmosphere.
