Polyacrylonitrile-based (PAN) graphite fiber felt
- Product Description
-
It boasts advantages such as light weight, high carbon content, excellent high‑temperature resistance, superior fiber strength, and outstanding shape‑formability. It is suitable for high‑temperature environments under vacuum or inert gas protection, with service temperatures exceeding 3,000°C, good thermal stability at elevated temperatures, and a long service life. Its primary applications include high‑temperature thermal fields in single‑crystal growth furnaces, polycrystalline ingot casting furnaces, vacuum heat‑treatment furnaces, cemented carbide sintering furnaces, and medium‑frequency induction furnaces.
