Product Description
Graphite felt is a felt-like material made from carbon fiber or synthetic fiber through special processes, with graphite as its main component.
-
Manufacturing Process
Usually, raw materials such as carbon fiber are carbonized at a high temperature (generally over 2,000 °C). During this process, non-carbon elements in the fiber are removed. Then, it is further processed in a graphitization furnace, where carbon atoms are rearranged to form a graphite crystal structure, and finally graphite felt is produced. In this process, the fibers are intertwined with each other, forming a felt-like structure with a certain thickness and elasticity.

Performance Characteristics
- Good High-Temperature Resistance: Graphite felt can withstand extremely high temperatures and can generally be used for a long time in a high-temperature environment of around 3,000 °C. This is because graphite itself has a high melting point and good thermal stability, enabling graphite felt to play an important role as a heat insulation material in high-temperature industrial furnaces, metallurgy and other fields. For example, in steelmaking furnaces, graphite felt can be used to wrap certain parts of the furnace body to reduce heat loss and improve energy utilization efficiency.
- Excellent Thermal Conductivity: It has a relatively high thermal conductivity and can effectively transfer heat. This makes graphite felt useful in scenarios where rapid heat dissipation or even heat distribution is required. For example, in the semiconductor manufacturing process, graphite felt can be used as a heat dissipation material to help electronic components such as chips dissipate heat quickly and ensure their normal operation.
- Good Chemical Stability: Graphite felt has relatively strong tolerance to most chemical substances. It is not easy to undergo chemical reactions in chemical environments such as acids and alkalis. Therefore, it can be used for filtration, adsorption and other operations in the chemical industry and can maintain stable performance for a long time.
- Good Flexibility and Processability: Although graphite felt is mainly composed of graphite, it has a certain degree of flexibility. It can be cut, folded, sewn and other processing operations according to actual needs, which is convenient for making products of various shapes and sizes to meet different application requirements.
- Application Fields
- Industrial Furnace Field: It is used as a heat insulation material in high-temperature industrial furnaces (such as vacuum furnaces, resistance furnaces, etc.), which can reduce heat loss, lower energy consumption, and at the same time protect the equipment and personnel around the furnace body from high-temperature damage.
- Metallurgical Industry: It is used for heat preservation and heat insulation in the metal melting process. For example, in melting furnaces for non-ferrous metals such as aluminum and copper, graphite felt can improve the melting efficiency and reduce metal oxidation.
- Electronic Industry: It is used as a heat dissipation material for electronic components (such as computer CPUs, power amplifiers, etc.) to ensure the stability of electronic equipment under high-load working conditions.
- Chemical Industry: It can be used as a filtering material. Utilizing its chemical stability and porous structure, it can filter impurities and harmful substances in the chemical process. It can also be used as an adsorption material to adsorb certain specific chemical substances.
- New Energy Field: In new energy equipment such as lithium batteries and fuel cells, graphite felt can be used as electrode materials or diaphragm materials, which helps to improve the performance and lifespan of batteries.
