Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Additional information

TFE is normally manufactured in a closed system. TFE vapours from vented equipment and tanks are destroyed by thermal oxidation. The use of TFE in fluoropolymer synthesis, nitroso-rubbers and low molecular mass compounded intermediates may result in its release to the environment through various waste streams.

In TFE-based polymer powders or granules, residual TFE monomer is not detectable (limit of detection 0.01 - 1 mg/kg). Due to its water solubility (110 mg/l) TFE monomer is always present in aqueous polymer dispersions at concentrations up to 1mg/kg, typically around 0.5mg/kg.

No residual TFE monomer (analytical detection limit 0.05 - 0.01 mg/kg) was found in PTFE at temperatures below 260°C, the maximum recommended "continuous service temperature".

No TFE (residual monomer) has been detected in products or articles made from TFE-based polymer.

The theoretical distribution of TFE into different environmental compartments has been estimated using the Mackay Level 1 fugacity model (Mackay and Paterson, 1981) and physico-chemical parameters.After equilibrium, practically all TFE released into the environment will be found in the air (99.99%). The amounts in water, soil and sediment are negligible.
