Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance non-graphitic carbon fibre is regarded as persistent, not toxic and not bioaccumulating.
According to the manufacturing process and with respect to its chemical composition the substance is regarded as inorganic: organic precursor materials are first oxidised at temperatures of approximately 300 °C and then carbonised in an inert atmosphere (e.g. nitrogen) at temperatures of approximately 900-2500 °C to drive off non-carbon atoms. The resulting material is therefore not expected to contain organic groups in amounts higher than traces.
Based on this information, the test results on toxicological endpoints, the substance's inertness to microbial activity and the results on other aquatic toxicity tests it is unlikely that the substance is harmful to aquatic or terrestrial life. Therefore, the T criterion is not fulfilled.
Based on the test results for the solubility in water together with the chemical nature of the substance the B criterion is not fulfilled.
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.
