Expandable Graphite/Flexible Graphite/Carbon Stone
Product Description
Expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates while heated. Once heated, it consequences an boom withinside the extent of as much as four hundred times, a decreasing of bulk density, and about a 10-fold boom in floor area. Then it’s compressed right into a tremendously cohesive bendy sheet.
