Expanded Graphite Rolls

	Sealing of Glands
	Gaskets used in flanges, covers, etc
	Rolled material can be used on automatic production lines

Natural graphite flakes are chemically treated to form a graphite compound. This is then rapidly heated to decomposition. The result of this is a rapid expansion of the graphite particle. These particles are then formed into graphite sheets by a rolling process.
