Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Hydrolysis of sulphur hexafluoride is unlikely to occur as it contains no hydrolysable functional group in its structure.
The atmospheric lifetime of SF6 was estimated by Ravishankara et al. (1993). The reaction of SF6 with O(1D) and the photolysis mediated by Lyman radiation were considered as the possible degradation pathways. The degradation rate coefficient for reaction of SF6 with O(1D) was estimated to be 1.5 x 10 -14 cm3/mol/s (1.80 ± 0.26 x 10 -14 cm3/mol/s). The OH-mediated photodegradation was considered as not relevant.
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.
