PRODUCTION DESCRIPTION:
Flake graphite is probably the most familiar of the natural graphite materials. Most people are familiar with the finely powdered graphite used as a lubricant, or the “lead” in pencils. Both of these products typically contain flake graphite. As the name implies flake graphite has a distinctly flaky or platy morphology. All graphite has a flaky morphology on some level, but in most instances flake-graphite has this structure regardless of particle size. Natural amorphous and fine flake graphite are used in brake linings or brake shoes for heavier (non-automotive) vehicles, and became important with the need to substitute for asbestos. This use has been important for quite some time, but non-asbestos organic (NAO) compositions are beginning to cost graphite market share. A brake-lining industry shake-out with some plant closures has not helped either, nor has an indifferent automotive market.
