Description of key information
Preliminary TGA
Instrument: Q50 thermogravimetric analyzer (TGA) (TA Instruments, USA)
Sample container: aluminum, closed with a lid in which a small hole was drilled
5.82 mg test substance was heated with a rate of 20°C/minute from 25°C to 401°C. At this point 70% weight loss of the test substance was observed. After the experiment, the sample was cooled to 50°C and the consistency of the test substance was determined.
DSC experiment
Instrument: Q100 differential scanning calorimeter (TA Instruments, USA)
Sample container: aluminum, closed with a lid in which a small hole was drilled
Reference: empty sample container
4.79 mg test substance was heated with a rate of 20°C/minute from 25°C to 374°C.
The experiments were performed under a flow of nitrogen and at atmospheric pressure.
Key value for chemical safety assessment
Additional information
Corfree® M1 diacid mixture has no boiling temperature. The substance decomposes at > 200°C.
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.
