Reinforced composite hard felt, graphite hard felt (commonly known as carbon fiber composite hard felt, cured felt, etc.) carbon fiber-reinforced) is a kind of graphite paper, polyacrylonitrile-based carbon felt, polyacrylonitrile-based carbon that uses a special process The whole fabric is integrated into one piece. It is made by one and two high-temperature treatments after solidification and molding. Its ablation resistance, thermal shock resistance, airflow resistance and heat insulation performance are all excellent.
It has the advantages of rigidity, self-support, high strength, no short fiber shedding, and low thermal conductivity that traditional insulation materials do not have.
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 sintering furnace , pressurized Vacuum Sintering Furnace, etc., which are widely used in national defense, metallurgy, chemical industry and other industries. Especially with the rapid development of polycrystalline silicon and monocrystalline silicon industry, as an ideal material for thermal field insulation of high-temperature furnaces, there is a demand for high-quality hard carbon fiber felt It has reached unprecedented heights.

Our company is an agent for efficient and professional hard felt insulation barrels, hard felt insulation boards, special-shaped parts, etc. It can produce various non-standard and special geometric shapes such as flat plates, discs, cones (disks), cylinders, etc.! Can provide hot cell assembly modification or installation services
