Ann: Updated research report, page-40

Hi names,

Nothing that I have officially seen...

This is from gpx website describing it as volume..... So hard to think they would define this here and report differently....



The expansion ratio is the volume of expandable graphite produced per gram of graphite product at a specified temperature. In general, coarser flake graphite typically has higher expansion ratios than smaller flakes. Producing expandable graphite is a relatively inexpensive process. Importantly, excellent rates of expansion can be achieved at low temperatures.



Also, I believe suzhou's own proprietary technology/treatment helps them achieve such a result.... A combination of both a great treatment and a brilliant product.
