|
| |
|
Flexible Graphite Yarn is made of Pure Flexible Graphite Tape. It is twisted and treated by special process and treatment. During the process, the graphite is reinforced with threads of cotton or other materials. It is suitable for sealing under different media, circumstances, temperature, and pressure.
Flexible Graphite Yarn is the basic material for braided packing.
APPLICATIONS
- Braided graphite packing .Braided sleeves or tubes
- Woven cloths and woven tapes
- Emergency repair tool for leaking pumps and valves.
