Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.:
ca. 0 °C
Atm. press.:
ca. 1 013 hPa
Decomposition:
no
Sublimation:
no
Remarks on result:
other: pour point
Remarks:
The pour point, the lowest temeprature at which the test material barely flows is at approximately 0 °C.

Any other information on results incl. tables

Measurements were made with differential scanning calorimetry in a temperature range between -100 and + 60 °C, but there was no possibility to determine a fixed melting point because the substance congealed amorphous and glassy. In the DSC diagrams there was only a glas transition at approximately -50 °C.

The pour point, the lowest temperature at which the testing material barely flows was at approx. 0 °C.

Applicant's summary and conclusion

Conclusions:
A pour point was determined at approximately 0 °C.
