Flexible Graphite Chemical Compatibility

MinGraph® flexible graphite is inert and resistant to nearly all organic and inorganic medium with exceptions of a few highly oxidizing concentrated chemicals such as high concentration of nitric or sulfuric acids, concentrated nitrates, persulfates, perbenzoate, and peroxides, molten sodium or potassium hydroxide and chlorine dioxide. (MinGraph® flexible graphite may still be compatible with such chemicals in certain concentration, environment or process, however, a compatibility test is recommended before it is implemented in such chemicals.). The following chart provides a list of chemicals, concentration and temperature range that are suitable for flexible graphite applications.
