Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The test item was found to be thermally stable.
Executive summary:

A study was conducted according to OECD TG 133 to determine the thermal stability of the test item using DSC measurement. The test item was weighed in under an inert atmosphere (nitrogen) into the closed crucible. As reference crucible, an empty crucible was used. For the test on thermal stability, the crucibles were heated up from room temperature to 500 °C with a heating rate of 3 K/min. The test item in a closed crucible showed an exothermic effect in the temperature range of 360 – 460 °C and a second one in the temperature range of 340 - 440 °C, with an overall decomposition energy of >500 J/g. According to the OECD guideline 113 criteria, the test item was considered to be thermally stable at room temperature as no decomposition or chemical transformation was found below 150 °C.
