Fiber Formed Rigid Felt is a low density, rigid, carbon fiber insulation material designed to perform at high temperatures in vacuum and inert furnaces.  Fiber Formed Rigid Felt can be supplied with a variety of coatings from QTC-2 graphite reflective paint for applications requiring a greater resistance to physical or chemical attack.  Horizontal fiber orientation of this Fiber Formed Rigid Felt insulation results in excellent through-the-thickness thermal insulation properties.
