Reference
Results
The test item did not emit any distinct endothermic signal that could be assigned with melting of the test item under discribed test conditions (up to 500 °C, 10 K/min, N2). Therefore, the test item does not melt at temperatures up to 500 °C.

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.
