Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables
The theoretical distribution of TFE into different compartments of the environment has been estimated using the Mackay Level 1 fugacity model (Mackay and Paterson, 1981) and physico-chemical parameters. The results are given below.
| Air | 99.99% |
| Water | 0.008% |
| Soil | <0.001% |
| Sediment | <0.001% |
| Suspended sediment | <0.001% |
| Fish | <0.001% |
| Aerosol | <0.001% |
These estmates show that, after equilibrium, practically all TFE released into the enviromnent will be found in the air. The amounts in water, soil and sediment are negligible.
Applicant's summary and conclusion
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.
