Flexible Graphite Rolls/Pure Graphite Sheet
Item No:ZD-PS2100

Description:Expanded graphite rolls(sheeting) is made of natural graphite flake.Expanded graphite rolls is actually chemically 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 is used as glands.It can also be cut into gaskets used in flanges.It can be used 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 lines.
