Expanded/Flexible Graphite Materials. Expanded graphite materials are derived from naturally occurring flake graphite The flake is chemically intercalated and then heated to expand the graphite The expanded graphite is then gradually compressed into a mat form The mat blank is then compression molded into a half-plate comprising gas and coolant channels The graphite preform is Heat-conducting plate of expanded graphite, composite Therefore, a method is set forth with which such heat-conducting plates that are made of expanded graphite can be produced in a continuous manner. The production of expanded graphite (expanded graphite material) is known, inter alia, from U.S. Pat. No. 3,404,061.
