    Hard composite carbon fiber felt(High purity product)

    Hard composite carbon fiber felt is processed by special technology of solidification and setting, and secondary high-temperature purification treatment with graphite foil, polyacrylonitrile base carbon felt and polyacrylonitrile base carbon cloth as the raw materials. Its ablative resistance, thermal shock resistance, airflow resistance, thermal insulation performances are very good, so it is mainly used in vacuum metallurgy industrial furnaces (high pressure gas quenching furnace, low pressure sintering furnace, pressure vacuum sintering furnace).

    Hard felt cylinder for heat preservation

    In the photovoltaic industry, the special graphite products used in polysilicon production include: reactors, polycrystalline cards, gas distributors, heating elements, heat shields and heat preservation tubes. In Siemens reduction furnace and STC-TCS hydrogenation furnace for recovering process gas, there are generally 1000 ° C (1800 ° f) high temperature and high corrosion environment. Our graphite parts are particularly suitable for this application due to their high heat and corrosion resistance.
