GRAPH-LOCK® 3123: The graphite flake has been acid washed, expanded under heat, and then compressed into sheets with a minimum graphite content of 98%. For thicknesses under 1/16” homogenous graphite is used. For thicknesses over 1/16” laminated graphite is used. The laminated graphite sheets are bonded with a proprietary adhesive.
