Graphoil ribbon is slit and corrugated (crinkled) from industrial-grade GR99 graphite material. Most flexible graphites have a carbon content of 95%–98%. We provide a high purity content of 99% carbon. This allows for better chemical resistance, thermal conductivity, and sealing.

Graphoil ribbon can be used as a valve stem package, gasket, or seal. It can also be used to make dieformed rings. Standard tapes are supplied without special treatments.
We offer graphite crinkle ribbon in standard thicknesses of 0.015" by 50' lengths. The available widths are 1/2" and 3/4".

See our graphoil ribbon literature for more information.
