Results in detail
Melting temperature
No melting temperature was found between -100 °C and 70 °C, even by addition of aluminum oxide powder as crystallization aid and annealing at -50 °C and -40 °C.
A reproducible glass transition was found at -77 °C in the 1st heating (determination Test 2, 4, 6, 7, A and 8).

The estimated accuracy is ± 1 °C.
Observed thermic processes
n order to survey the thermic behavior of the test item a preliminary TG/DSC-Test (non-GLP) was run up to 600 °C. An endothermic peak starting at about 100 °C with a total weight lass at 250 °c showed the vaporization of the test item.
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.
