- Conclusions:
- With the previous test, decomposition point, no melting point was seen. The melting point was not determined. The glass transition temperature is -40.7 °C.
- Executive summary:
With the previous test, decomposition point, no melting point was seen. The melting point was not determined. The glass transition temperature is -40.7 °C. Due to the glas transition the test item has no melting point (Currenta, 2009).
Reference
- The substance does not have a melting point.
- The substance has a glass transition temperature of - 40.7 °C and a boiling range.
- A decomposition was not seen.
Description of key information
With the previous test no melting point was seen. The glass transition temperature is -40.7 °C. Due to the glass transition the test item has no melting point (Currenta, 2009).
Key value for chemical safety assessment
Additional information
The substance has a glass transition temperature and a boiling range. A decomposition was not seen.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
