## Thermal textile for stitching and auxiliary sealing

Graphite thread is produced from fibers subjected to carbonization and graphitization processes. The result is a high-temperature-resistant thread with low friction and good stability against aggressive media.

ESGRAF supplies it for **sewing soft felts**, fabricating packing reinforcements, tying elements in furnaces and other applications requiring a flexible element that does not degrade with heat.

## Typical applications

- Joining and reinforcing [soft felt](https://esgraf.com/en/materials/felts-foils-packing-others/soft) in heat-treatment and vacuum furnaces.
- Complement in sealing systems together with [braided packing](https://esgraf.com/en/materials/felts-foils-packing-others/braided-graphite) or [flexible laminates](https://esgraf.com/en/materials/felts-foils-packing-others/gaskets).
- Liners, ties and auxiliary elements in high-temperature equipment.

## Service properties

- Thermal resistance in inert or controlled atmospheres.
- Low friction and good thermal conductivity compared to organic fibers.
- Superior chemical resistance to conventional threads in aggressive media.

> Do not confuse with **structural carbon fiber (HT/UHT)**: graphite thread is intended for textile and insulation applications, not structural mechanical loads such as aerospace composites.

## Information for quoting

Provide diameter or count, required length or weight, application (felt stitching, packing, static/dynamic sealing), maximum temperature, working atmosphere and quantity.
