- other: density of the sample to water at 4°C
- Conclusions:
- The density of the sample was determined to be 2.2591 g/cm3 which corresponds to a relative density of 2.2591 (to water at 4 °C).
- Executive summary:
The density of the sample was determined in a non-GLP study according ASTM D 5550 with a gas pycnometer. The density of the sample was determined to be 2.2591 g/cm³ at about 20 °C which corresponds to a relative density of 2.2591 (to water at 4 °C).

Description of key information
The density of the graphene was determined in a non-GLP study according ASTM D 5550 with a gas pycnometer. The density of the sample was determined to be 2.2591 g/cm³ at about 20 °C which corresponds to a relative density of 2.2591 (to water at 4 °C).
This is also supported by the density-value for graphite which contains several graphen-layers which are connected to each other by π-π-interactions. The graphite density has a value of 2.26 g/cm³ (Hollemann/Wiberg, 2017).
Key value for chemical safety assessment
- Relative density at 20C:
- 2.259
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
