Flexicarb is an exfoliated graphite material with standard grades at 95% to 98% and a nuclear grade available at 99.5%. It can be supplied with an inorganic passivating inhibitor to increase its oxidation and corrosion resistance. Recent experiences and tests have shown that Flexicarb will oxidize over time. Care should be taken when considering the use of Flexicarb foil for applications above 330°C (650°F).
(Note: Flexicarb ST, SR and NR are the equivalents for Flexicarb RGS1, RGS3 and RGS4 which are the brand names used in the UK.)
