Reinforced Composite Rigid Felt, Graphite Rigid Felt (commonly also referred to as carbon fiber-reinforced composite rigid felt, solidified felt, etc.) is manufactured by integrating graphite paper, polyacrylonitrile-based carbon felt, and polyacrylonitrile-based carbon cloth into a unified whole using a special process. After solidification molding, it undergoes primary and secondary high-temperature treatments. Its ablation resistance, thermal shock resistance, resistance to gas flow erosion, and thermal insulation performance are all excellent.

It possesses advantages that traditional insulation materials lack, such as rigidity, self-supporting capability, high strength, no short fiber shedding, and low thermal conductivity. It is mainly used in vacuum furnaces and various types of metallurgical industrial furnaces (including monocrystalline silicon growth furnaces, polycrystalline silicon casting furnaces, polycrystalline silicon reduction furnaces, polycrystalline silicon ingot furnaces, high-pressure gas quenching furnaces, hot isostatic pressing furnaces, thermal equilibrium furnaces, low-pressure sintering furnaces, and pressurized vacuum sintering furnaces). It is widely applied in industries such as national defense, metallurgy, and chemicals. Particularly with the rapid development of the polycrystalline silicon and monocrystalline silicon industries, the demand for high-quality rigid carbon fiber felt, as an ideal thermal insulation material for high-temperature furnace hot zones, has reached an unprecedented level.

Our company acts as an agency, supplying efficient and professional rigid felt insulation cylinders, rigid felt insulation boards/sheets, and custom-shaped components. We can fabricate various non-standard and custom geometries, including flat plates, disks, conical cylinders (disks), and cylinders. Services for hot zone assembly modification or installation are also available.
