Carbon & Graphite Felt
Carbon and Graphite felt is a soft flexible high-temperature refractory insulation typically used in vacuum and protected atmosphere environments up to 5432℉ (3000℃). High purity felt heat-treated to 4712℉(2600℃) and Halogen Purification are available for custom production orders. Additionally, the material can be used in oxidizing temperatures up to 752℉ (400℃).
the difference between Pan & Rayon Felts
Polyacrylonitrile, also known as PAN, is manufactured with larger diameter course fibers resulting in lower surface area and better oxidation resistance. The flexible material is stiffer and less soft to the touch in comparison to Rayon. Thermal conductivity of Rayon is lower than PAN at temperatures greater than 3272℉ (1800℃).
