Good Morning Ash,

Graphene is determined by its thickness, not its lateral platelet size i.e. if the graphene is 1m2 and only 1-10 layers think. it is still graphene, FLG, or GNP.

Different-sized platelets have different properties or benefits. it's not as simple as one-size graphene platelet works in all applications. A large platelet graphene isn't going to be suitable for ink, or the 1um graphene isn't going to be suitable in concrete.

The grinding aid uses a 50-70 micron graphene nano platelet. The size of the platelet is around half the size of a medium-diameter human hair.
