Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results in detail

Melting temperature

No melting temperature was found between 0 °C and decomposition of the test item, starting at about 300 °C (Test 2, 1st


The estimated accuracy is ± 1 °C.

Observed thermic processes

After Test 1 and Test 2 the test item was not molten up and did not show any visual change. This was a clear indication that the

observed exothermic peak starting at about 300 °C and the registered weight loss of 45.6 % showed the decomposition of the

test item (Test 2).

These observations are confirmed by the preliminary TG/DTA-Test (non-GLP). An exothermic peak at about 360 °C peak temperature with a weight loss of 45.9 % at 400 °C showed the decomposition of the test item.

The stepwise weight loss up to about 17 % at 250 °C was interpreted as the loss of humidity and volatile components. This

may be caused by an open handling during the preparation of the crucible before the TG/DTA measurement.
