The matrix of cells and ligaments is completely repeatable, regular, and uniform throughout the entirety of the material. Baltek carbon RVC is a rigid, highly porous and permeable structure and has a controlled density of carbon per unit volume.

Flexible Graphite Felt Thermal Insulation

Pan (Polyacrylonitrile based) carbon felts.

Rayon (viscose-based based) graphite felts.

carbon felt

BALSGF is available as either Pan or Rayon based graphite felts.
The flexibility of the felt allows the insulation to be shaped around the walls of the furnace often it is utilized as a protective barrier between the furnace wall and the rigid insulation to take out any irregularities and also to compensate for differential expansion between the two different materials.
