no
Remarks on result:
other: Glass transition temperature is - 40.7 °C.

- 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.

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).

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
