Graphite Crinkle Ribbon
The graphite ribbon is slit and corrugated (crinkled) from industrial grade graphite material. Most flexible graphite in the market has a carbon content ranging from 95% -99%. The flexible graphite foil we use has a high purity content of 99% carbon. A higher carbon content gives the flexible graphite better chemical resistance, better thermal conductivity, and better sealability.
Widely used in pumps, valves, mixers, agitators for sealing purposes. It can also be used to encapsulate & enhance the sealing efficiency of other gaskets types such as PTFE, Asbestos, Spiral Wound, Metallic & other gasketing materials.
