Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

1 Total heating time 300 seconds

The test substance was non-explosive to mechanical stress by shock. When a 10 kg mass was dropped on the test substance from a height of 0.4 meter, no traces of vigourous reactions were observed.

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
No positive results were obtained when testing according to EU Method A.14, therefore the test substance was not considered an explosion hazard.

Description of key information

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

mmt is not explosive when exposed to thermal stress or mechanical stress by shock.
