Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The kinematic viscosity of HFP kinetic dimer is 0.3576 mm2/s at 20 °C and 0.3012 mm2/s at 35 °C.
Key value for chemical safety assessment
Additional information
In the key study, the kinematic viscosity was measured using a SCHOTT Ubbelohde 545-01 capillary viscometer. While no specific guideline was cited and the study was not done under GLP criteria, Ubbelohde viscometers are described in ISO3104, which is an approved method in OECD TG114. Therefore, it is considered reliable with restrictions. Another value for viscosity was found in a summary document on substance properties. However, due to few details available, it cannot be classified as to its reliability.
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.
