- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- -3 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: No melting was observed between -150°C and +50°C; the value reported is a glass transition temperature
- Conclusions:
- Under the conditions of the study, no melting point was determined but a glass transition was observed at -3 °C.
- Executive summary:
The melting temperature of the substance was studied by differential scanning calorimetry (DSC) according to OECD Test Guideline 102 and EU test method A.1 “Melting/freezing temperature. The test material was cooled until -150°C and then heat until +50°C. No melting point was found between -150 and +50°C. A glass transition was observed at -3°C.
Reference
Upon heating the test material has solidified amorphously and no other thermal effects were observed.
Description of key information
No melting/freezing point is available. A glass transition was observed at -3 °C.
Key value for chemical safety assessment
Additional information
