Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Melting / freezing point
Key result
Melting / freezing pt.:
-57.4 °C
Atm. press.:
1 atm
Decomposition:
no
Sublimation:
no
Remarks on result:
not determinable
Remarks:
The sample does not display a freezing point on cooling. A melting point was not evident on heating. The sample shows a glass transition with an average onset of 215.9°K (-57.4°C). It is possible the sample has a melting or freezing point below -90°C. However, the glass transition indicates that the sample is amorphous rather than crystalline.

Applicant's summary and conclusion

Conclusions:
Glass transition with an average onset of 215.9°K (-57.4°C).
