Soft Felt

Soft felts are flexible insulation materials for high temperature applications in inert or vacuum atmospheres and consist purely of carbon Fibers 

Soft Felt Manufacturing 

The base material for the production of carbon and graphite soft felt is felts made of needled cellulose fibers. These are processed into carbon soft felts by thermal treatment at 800-1,000°C. If these felts are treated at even higher temperatures >2,000°C, the carbon fibers increasingly take on a graphite-like structure.
