1. Reaction: endothermic

- onset temperature: -20 °C

- peak temperature: 10 °C

- used heat quantity: 180 J/g

The reaction was not tested for self-accelerating decomposition behaviour.

2. Reaktion: exothermic

- onset temperature: 280 °C

- peak temperature: 388 °C

- released heat content: 1420 J/g

The reaction is self-accelerating.

Description of key information

The test item is considered to be thermaly stable at room temperature.

Additional information

A key study (BASF SE, SIK 11/1957) following the procedure in DIN 51007 was performed. The sample was observed to undergo one endothermic event during the test with an onset temperature of -20 °C with energy consumption of 180 J/g, as well as one exothermic and self accelerating event with an onset temperature of 280 °C and an energy release of 1420 J/g.

A supporting study (BASF SE, SIK 85/0293) following a procedure equivalent to DIN 51007 was performed. The sample was observed to undergo an exothermic event during the test starting at an onset temperature of 190 °C with an maximum at 270 °C and an energy release of 1200 J/g .

In both studies insignificant thermal transformation has occured below 150 °C with energy release < 100 J/g. Therefore, the test item is

considered to be thermaly stable at room temperature.
