- Executive summary:
Method
The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.
Result
Between 28 -155 °C (onset at 28°C, enthalpy = -185 J/g) an endothermic peak was recorded, followed by a exothermic peak related to degradation of the product from 350 °C.
