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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
The substance does not have a melting point, however it has a glass transition.
Glass transition is determined at 20 °C/min. Midpoint is taken for glass transition. Midpoint is defined as the middle of the step. The accuracy of the evaluation of the glass transition is dependent of the baseline and the type of product.
Description of key information
Glass transition: -98 °C at ca. 1013 hPa (Differential Scanning calorimetry)
Key value for chemical safety assessment
Additional information
The substance does not have a melting point, however it has a glass transition.
There are no values given for pressure but assumed to be measured at normal pressure (1013 hPa).
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.
