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).

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.
