Results and discussion

Melting / freezing point
Melting / freezing pt.:
°C
Decomposition:
yes
Decomp. temp.:
> 300 °C

Any other information on results incl. tables

No melting point could be determined. The TGA points to decomposition well above 300 °C.

Applicant's summary and conclusion

Conclusions:
The decomposition temperature of the test substance is above 300 °C.
Executive summary:

When tested in a study using methods based on OECD guidelines and EU test methods, the test substance showed no melting point up to 300°C with decomposition taking place well above 300°C.
