Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Conclusions:
- The melting and freezing points of the samples were determined using DSC. None of the samples has a
freezing point, melting point, or Tg. Because the DSC results were inconclusive, the samples were also
analyzed by DMA by slowly cooling the sample and monitoring the rise in viscosity. Normally a material that
freezes undergoes a sharp increase in viscosity. EP-AT-N 5 has a gradual increase in viscosity. The extrapolated
freezing point is -63°C and should be taken as the center of a range of freezing rather than a distinct freezing point. EP-AT-N 01 has a gradual increase in viscosity. The extrapolated freezing point is -66°C and should be taken as the center of a range of freezing rather than a distinct freezing point. - Executive summary:

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
