Reference
Results
No melting peak was seen in the heating cycle. A relaxation peak and an
endothermic Cp-step at - 36 °C (2nd heating) can be seen
in the DSC curve, which is characteristic of a glass transition. The
test item solidifies amorphously in the glassy state. No melting point
was detected.
Description of key information
No melting point detected, the test item solidifies amorphously in the glassy state at ca. -36 °C (OECD 102, DSC).
Key value for chemical safety assessment
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.
