Vulcan uses unique air-laid technology, high uniformity, ideal fiber network structure for chemical properties, good felt stretch and strength, and special manufacturing process to produce graphite soft felt with high thermal insulation and high purity.

At present, Vulcan has mastered all carbon fiber felting technologies, and has independently developed solidified felts using carbon fiber soft felt as raw material, and has been graphitized at 2400℃ for one-step forming. The hard felt adopts density gradient structure technology, and undergoes various surface treatments or purification treatments, which have higher strength, better oxidation resistance, and higher porosity. All felting equipment, impregnation equipment, solidification equipment, carbonization and graphitization equipment, and high-temperature chemical purification equipment are independently developed.

C/C Composite structural materials are particularly suitable for use in high-temperature furnaces or chemical processing technology environments under inert atmosphere or vacuum environments. Using advanced 3D structural forming plates, high-quality processes and reliable diamond tool equipment processing ensures its structural strength in the use environment. Through non-destructive and destructive tests, high reliability is ensured during use.

The absolutely leading purification process in China can purify the purity to below 5ppm, with a purification depth of 50mm on one side. At the same time, it can release the processing stress to reduce the deformation of graphite materials in the ultra-high temperature environment of the thermal field and improve the product life.
