With the substance
1. as delivered, a self-heating was not detected until 420°C. Above the melting point the test item melted and flew out of the wire basket without showing an oxidising reaction.
2. in mixture with kieselguhr (1:1) a first reaction was detected at 270°C which was intensified from 300°C to a maximum temperature of 600°C. The beginning of the reaction at 270°C corresponds to the exothermal reaction in the thermal stability test (closed glass crucibles).
Applicant's summary and conclusion
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.
