Flexible expanded graphite sheet/graphite foil
WL-GS1000
Description
Expanded graphite rolls(sheet) are made of natural graphite flake, it's actually treated graphite intercalation compound. This intercalation compound is then rapidly heated to decomposition. The result is a rapid expansion of the particle size. The bulk density of the worm-like graphite powders is about 0.003g/cc. Then they are formed into graphite sheets by rolling. Expanded graphite rolls are used as glands, it can be cut into gaskets used in flanges, and as covers of observation holes, level meters. It can be directly attach to the metal surfaces for gas phase sealing effectively. Especially the expanded graphite rolls can be used as a material for automatic producing line.
