Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Additional information:
- ASSEMBLY STRUCTURE:
The inner diameter of the individual multiwalled carbon nanotubes that are part of the carbon nanostructures ranges from 3-8 nm and the outer diameter ranges from 5 to 20 nm, The number of walls ranges from 2-14. Carbon nanostructures (CNS) are cross linked and branched multiwalled carbon nanotubes in which internal carbon nanotube walls are shared between adjacent tubes and can be considered a highly structurally entangled polymer of multi-walled carbon nanotubes.
RIGIDITY:
CNS structure is not rigid. It can be considered a highly entangled polymer of multi-walled carbon nanotubes. The final particle size of CNS flakes is micron-sized (approximately 20µ to 120µ in three dimensions). TEM images are shown in Section 1.4. - Fraction of constituent particles in the size range 1-100 nm:
