Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

With the substance

1. as delivered, a self-heating was detected at 180°C. In the temperature range of 180 - 300°C several small effects were observed which caused only slight temperature increase. At 300°C the test item melted and flew out of the wire basket. The beginning of the self-heating at 180°C corresponds to the beginning of the exothermal oxidation reaction in the DSC under 20 bar air.

2. in mixture with kieselguhr (1:1) a reaction was detected at 290°C which led to a maximum temperature of 750°C. The beginning of the reaction at 290°C corresponds to the exothermal reaction in the thermal stability test (closed glass crucibles).
