Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Decomposition from 350°C, Melting point > 438 °C, OECD 102, EU Method A.1, Licata-Messana 1998a
Key value for chemical safety assessment
Additional information
The melting point of the test material was determined in accordance with standardised guidelines OECD 102 and EU Method A.1 using both the Kofler hot bar method and the capillary method. During testing the Kofler hot bar method showed that the melting point of the test material was higher than 260 °C. Therefore, the capillary method was used in the main test. On heating, the test material shrivelled and became black at temperatures of 350 ± 3 °C. No melting point was observed up to 438 °C.
The study was performed in line with GLP and accepted standardised guidelines with a high level of reporting. The study was assigned a reliability score of 1 according to the criteria of Klimisch (1997) and considered suitable for assessment as an accurate reflection of the test material.
The available data are considered to be complete and the result determined, decomposition at approximately 350 °C, was carried forward for risk assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
