General description

Flake graphite is a naturally occurring form of graphite that is typically found as discrete flakes ranging in size from 50-800 μm in diameter and 1-150 μm thick. This form of graphite has a high degree of crystallinity, which equates to near theoretical true density, high thermal and electric conductivity and low springback (excellent molding characteristics).
