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.
