    Abstract: A release lined pressure sensitive adhesive flexible graphite sheet article is provided having low thermal resistance properties comparable to the flexible graphite material itself when compared to prior art PSA sheet products and wherein the release liner is easily removed with the sheet to be used without any significant delamination of the flexible graphite. The flexible graphite sheet comprises a flexible graphite substrate, an adhesive primer coating thereon, a pressure sensitive adhesive coating on the adhesive primer coating and a release liner applied to the pressure sensitive adhesive coating. Double sided pressure sensitive adhesive flexible graphite sheets can also be made using the method of the invention. It has been found that the use of an adhesive primer coating on the flexible graphite substrate applied from an emulsion as a coating and dried instead of the prior art adhesive containing polymer layer applied as a solid film, such as Mylar film, provide the above desired thermal resistance properties and also enable the use of less pressure sensitive adhesive on the sheet thereby maintaining the low thermal resistance properties of the flexible graphite.

    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.
