A material useful in a process for embossing a flexible graphite sheet is presented. The inventive material is a flexible graphite sheet which has a preselected void condition which provides the capability of controlling the morphology, and thus the functional characteristics, of the resulting embossed sheet (100).
Abstract:
The present invention relates to a compressed mass of expanded graphite particles in the form of aflexible graphite sheet (10). The flexible graphite sheet is formed from particles of expanded natural graphite formed from graphite flake sized no more than about 30 % by weight + 80 mesh prior to expansion. The flexible graphite sheet (10) is provided with channels (20) which are perferably smooth-sided as indicated at (67) in Figure 5 and which pass between the opposite surfaces (30) and (40) of flexible graphite sheet (10) and are separated by walls (3) of compressed expandable graphite. The channels preferably have openings (50) on one of the opposed surfaces (30) which are larger than the openings (60) in the other opposed surface (40).
