Method
Test carried out according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.
Result
Between 40 and 200 °C, there is an endothermic event, followed by a second endothermic event between 274 and 448 °C with decomposition.
Reference
Endothermic events:
40 - 200 °C (onset at 44.3 °C, enthalpy -350.4 J/g)
274 - 448 °C (onset at 310.9 °C, enthalpy -544.4 J/g) with decoposition
Description of key information
Endothermic events:
40 - 200 °C (onset at 44.3 °C, enthalpy -350.4 J/g)
274 - 448 °C (onset at 310.9 °C, enthalpy -544.4 J/g)
Key value for chemical safety assessment
