Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- > 600 °C
- Atm. press.:
- 1 013 mBar
- Remarks on result:
- other: The test item has no melting point under atmospheric conditions up to 600°C. There was no atmospheric pressure stated, it was assumed to be 1013mBar.
Any other information on results incl. tables
Thermal Stability
The DSC-measurement in a closed glass crucible with the test item showed no thermal effects in the temperature range 30 °C to 450 °C.
Melting Point / Melting Range (DSC)
The measurement in an aluminium crucible with a hole showed no significant endothermic effect or exothermic effects up to the maximum temperature of 600 °C. No mass loss was detected.
An optical inspection after the measurement showed that the test item was unchanged (regarding both the physical form and the colour of the test item).
Thus it was concluded, that the test item does not melt within the tested temperature range of 40 – 600 °C.
Applicant's summary and conclusion
- Conclusions:
- The test item has no melting point under atmospheric conditions up to 600°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
