What Is PAN Graphite Felt?
PAN graphite felt is a high-performance insulation material made from polyacrylonitrile (PAN) fibers that are carbonized and coated with graphite. This process creates a rigid yet flexible material that combines excellent thermal insulation with mechanical strength, making it ideal for high-temperature applications.
Manufacturing Process
PAN graphite felt is produced through a specialized process that involves carbonizing PAN fibers at high temperatures, followed by graphite coating. This enhances the material's ability to withstand extreme temperatures, making it the preferred choice for vacuum furnaces, heat treatment systems, and other high-heat environments.
Comparison with Rayon Graphite Felt
PAN graphite felt is stronger and more rigid than rayon graphite felt, offering superior mechanical strength and oxidation resistance. While rayon graphite felt is ideal for flexible applications, PAN graphite felt excels in high-pressure, high-temperature environments where structural stability is critical.
