SDS

• Carbon black, graphite, diamonds, buckyballs, and carbon nanotubes are all pure carbon just different molecular configurations (allotropes)!
• SDS for some commercially available carbon nanotubes refers to graphite PEL.
• Graphite is composed of coarse particles.
• Carbon nanotubes are shaped like fibers and behave much differently - graphite PEL is not applicable!
• The SDS is not always accurate because it may reference base chemical and not formulation or grade specific to nanomaterial.
