Description

Graphite (CAS 7782-42-5) is a naturally occurring crystalline form of carbon, also known by trade designations such as MG1, IG11, MPG6, PG50, and by the historical name plumbago. It carries no E-code designation and is classified under HS code 38011000. Both natural and synthetic grades are commercially available, sometimes blended or combined with additives.

In metalworking and lubrication, graphite reduces friction between sliding surfaces by forming a low-shear film that prevents direct metal-to-metal contact. In electronics manufacturing, it serves as a conductive coating and electrode material, where its layered carbon structure enables consistent electrical conductivity. Automotive applications include brake pad formulations, where it modulates friction coefficients under high thermal load.

Graphite is sourced in natural flake, amorphous, and synthetic forms, with purity grades selected according to application requirements. It falls under REACH regulation and requires a Safety Data Sheet for EU trade. Packaging typically follows bulk, big-bag, or drum formats depending on particle size and grade specification.
