Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results in detail:

No melting temperature was found between -100 °C and 40 °C, even by addition of aluminum oxide powder as crystallization aid

and annealing at -100 °C and -80 °C (determination Test 2).

A glass transition was found at -108 °C in the 1st heating.

Determination  glass transition temperature (°C) 
 Test 3  -107.79
 Test 4  -108.00
 mean value  -108

The glass transition was measured with a heating rate of 20 K/min according to DIN EN ISO 11357.

Observed thermal processes:

In order to survey the thermal behavior of the test item a TG/DSCTest

(non-GLP) was run up to 810 °C.

An endothermal peak starting at about 80 °C with a weight loss of about 99 % at 200 °C was observed. This is presumably due to the

the vaporization or decomposition of the test item.
