Explanations
Tm1= melting peak temperature in delivery condition
Tk* = crystallisation temperature
∆m = weight loss, determined at the end of the measurement
In a first measurement up to 160 ° C showed a strong thermal degradation of the sample with a weight loss of about 31%, so that a maximum temperature was chosen just above the melting peak for the present measurement
Applicant's summary and conclusion
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.
