Any other information on results incl. tables
A small endothermic heat effect was observed starting at about 220°C. An exothermic heat effect started at about 240°C to 400°C (20K/min). After the experiment, the sample had lost about 37% of its mass and the sample was black and carbonized. The degradation started at about 240°C. The test item didn't boil under ambient conditions. A further DSC-run was recorded as main study between about 25°C and 260°C with a heating rate of 10K/min. The endothemic reaction was determined to start at about 210°C. This is not due to the melting of the sample because at the end of the test, the sample was black and carbonized but not melted. The endothermic heat effect might have been caused by a change in crystalline structure. During this run, the sample lost 15% of its mass.
T002113 didn't melt under the conditions of the test.
Applicant's summary and conclusion
- Conclusions:
- T002113 did not melt under the conditions of the test.
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).
