Carbon and Graphite felt is a soft flexible high-temperature refractory insulation typically used in vacuum and protected atmosphere environments up to 5432ºF (3000ºC). High purity felt heat-treated to 4712ºF(2600ºC) and Halogen Purification are available for custom production orders. Additionally, the material can be used in oxidizing temperatures up to 752ºF (400ºC).
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 3272ºF (1800ºC).
For heat treat applications, our office highly recommends PAN carbon felt due to the materials handling ease and reduced price. If you are operating at temperatures greater than 3272ºF (1800ºC), please use Rayon.
