Graphite on commercial operations, concentrated sulfuric acid used as an interlayer inserts, so it is also called acidification graphite (expandable graphite). But after acidification graphite is graphite with an acid, washed and dried, between most layer insert has escaped, so it is actually between the residual graphite intercalation compounds. Between the majority of graphite intercalation compounds of graphite sold Lacey rapid heating, the insert will be gasified interlayer Lacey graphite, thereby forming a high pressure, expansion of the graphite particles along the C-axis direction. After acidification thin graphite flakes swell like a strip worm carbon graphite factory lengths up to 1 ~ 2cm so called worm graphite or graphite worms, that is commonly referred to as expanded graphite. Development and application of traditional gas-solid structure due to the flexible graphite flexible graphite to have good sealing performance, as the sealing material has a broad market. Especially the traditional sealing materials asbestos due to environmental pollution, by disabling, flexible graphite to provide opportunities for development. Depending on the requirements of the international community of users, we have developed a lot of new brands of advanced flexible graphite.
