The purified graphite soft felt has low ash and high purity, which ensures the purity of the thermal field.
It also has the characteristics of corrosion-resistant and anti-static, which is suitable for all kinds of harsh environments.
Graphite soft felt has very high thermal conductivity, which can effectively transfer heat and improve the thermal efficiency of the equipment.
It can remain stable in high temperature environment, the use temperature can reach 2000℃ or above, and even up to 3000℃ or so under certain conditions, no volatilization under high temperature.
Graphite soft felt is a special felt material with lightweight, soft and porous texture, easy to process into various shapes and sizes.

Yes, it can be cut, shaped, or impregnated with various materials (e.g., resins, oxidation inhibitors) to meet specific application requirements.
Yes, graphite felt has electrical conductivity, making it suitable for use in electrochemical applications, such as flow batteries and fuel cells. The conductivity depends on the graphitization level.
Graphite felt is produced by carbonizing precursor fibers (e.g., PAN or Rayon) at high temperatures, followed by further graphitization at 2,000–3,000°C to increase purity and crystallinity.
No, graphite felt oxidizes at high temperatures in an oxygen-rich environment. It should only be used in vacuum or inert atmospheres such as argon or nitrogen.
Graphite felt can typically withstand temperatures up to 2,200°C (3,992°F) in an inert atmosphere. The exact temperature resistance depends on the material purity and treatment.
Graphite felt is a high-purity, high-temperature-resistant material made from carbonized and graphitized fibers. It is commonly used as an insulating material in furnaces, batteries, and other high-temperature applications.
