Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 mean vapor pressure of the test substance, BPAF and BPAF:BTPP (1:1) Salt, was determined at 20 ± 1°C using the SRG method and was determined to be 4.01E-5 Pa.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

The vapor pressures of the test substance at 20 ± 1°C were below the recommended range of the SRG method (i.e. 1E-4 to 0.5 Pa).  The high variation at 10°C was due to the measurements being too close to the background vapor pressure of the SRG method.
