Carbon felt and graphite felt are designed for
use as high temperature insulation in
vacuum furnaces and inert gas furnaces. The
needle-punched PAN based carbon and
graphite felt is light in weight and has low
thermal conductivity. It can be used in
oxidizing temperatures up to 400 °C and in
vacuum or protective atmospheres up to 3200
°C
