    Graphite hard felt (commonly known as carbon fiber composite hard felt, cured felt, carbon fiber-reinforced, etc.) is made by a special process that integrates graphite paper, polyacrylonitrile-based carbon felt, and polyacrylonitrile-based carbon cloth into one body, curing After molding, then primary and secondary high-temperature treatment.


    Graphite Hard Felt Sheet is mainly used in vacuum and various metallurgical industrial furnaces (single crystal growth furnace, polycrystalline casting furnace, polycrystalline reduction furnace, polycrystalline ingot furnace, high-pressure gas quenching furnace, hot isostatic pressing furnace, thermal balance furnace, low-pressure sinter Furnace, pressure vacuum sintering furnace, etc.


    Graphite Hard Felt Sheet is also widely used in defense, metallurgy, chemical industry, and other industries.


    Especially with the rapid development of polycrystalline silicon and monocrystalline silicon industries,

    as an ideal material for thermal insulation of high-temperature furnaces, the demand for high-quality hard carbon fiber felt has reached an unprecedented height.


    The main use of Graphite Hard Felt Sheet is as a thermal 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. Under the non-oxidizing atmosphere, the temperature of the graphite felt can reach 2850℃.
