  • Oxidation and corrosion resistant flexible graphite composite sheet and method
    Patent number: 5981072
    Abstract: Flexible graphite sheet is made by compressing a mixture of fine particle of intercalated, exfoliated, expanded natural graphite with fine particles of intercalated, unexpanded, expandable particles of natural graphite admixed with small amounts of a phosphorous bearing compound, the unexpanded particles being more finely sized than the expanded particles. The resulting sheet of flexible graphite exhibits improved fire retardant and sealability properties and additionally resistance to oxidation and corrosion.
