Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with column 2 of REACH Annex VII, a relative density study (section 7.4) does not need to be conducted as the substance is a gas. An estimation based on calculation shall be made from molecular weight and the Ideal Gas Laws. The relative density with respect to air can be obtained by: RD = ρgas/ρair  = Mgas/Mair. As the molecular weight of air is 28.97 and the molecular weight of VDF is 64.04, the relative density is 64.04/28.97 = 2.21. Nevertheless data is available showing that vinylidene fluoride has a relative density of 0.59-0.62. This value refers to liquid vinylidene fluoride under its autogenous pressure (about 36 - 40 bar).

Key value for chemical safety assessment

Additional information

Non-guideline, non-GLP study, minor restrictions in design and/or reporting but adequate for assessment and data published in peer reviewed handbook, acceptable for assessment.
