Description of key information
Glass transition temperature: -107°C
Key value for chemical safety assessment
Additional information
The determination was conducted by DSC according to OECD Guideline 102.
No melting temperature was found between -100°C and 50°C, even by addition of aluminum oxide powder as crystallization aid.
A reproducible glass transition seemed to be at about -107°C. But this is not fully secured because the stability of the measuring instrument below -100°C is a little bit uncertain.
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.
