Description of key information

The viscostiy of PFBE was determined to be 0.375 mm2/s at 20°C and 0.307 mm2/s at 40°C.

Key value for chemical safety assessment

Viscosity:
0.375 mm²/s (static)
at the temperature of:
20 °C

Additional information

The viscosity of PFBE was determined using a capillary viscometer method, designed to be compatible with Method 114 of the OECD Guidelines for Testing of Chemicals, 2 October 2012. The results are as follows:

Temperature (°C)

Viscosity (mm2/s)

20.0 ± 0.5

0.375

40.0 ± 0.5

0.307
