Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Three reports are available for this endpoint. There are four experiments done with thermal analysis (DTA). Two of them were done at atmospheric pressure without air, and two of them were done with air. In all the tests a decomposition temperature is measured. When testing is done without air, the decomposition starts later (at 335°C and 350°C) with no melting before decomposition.
