Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Decomposition:
yes
Decomp. temp.:
> 353 - < 416 °C

Water/imbibition solvent release was observed between 83 °C and 120 °C, followed by a little endothermic event between 188 °C and 294 °C (onset at 205.7 °C, enthalpy: -23.2 J/g) and then decomposition between 353 °C and 416 °C (onset at 356.8 °C, enthalpy: 42.7 J/g).

Conclusions:
Decomposition between 353 °C and 416 °C, before melting.
Executive summary:

The test has been conducted according to the internal method SOP-STR 028, corresponding to the OECD 102, using DSC analysis.

Water/imbibition solvent release was observed between 83 °C and 120 °C, followed by a little endothermic event between 188 °C and 294 °C (onset at 205.7 °C, enthalpy: -23.2 J/g) and then decomposition between 353 °C and 416 °C (onset at 356.8 °C, enthalpy: 42.7 J/g).

Description of key information

Decomposition between 353 °C and 416 °C, before melting.

Key value for chemical safety assessment
