- Executive summary:
The test item has a vapour pressure of 0.00013 Pa at 20 °C, 0.00018 Pa at 25 °C and 0.00076 Pa at 50 °C.
Reference
Due to the fact that the test item is very viscous the test item was tempered at 50 °C. Afterwards a portion of the test item was cooled down with liquid nitrogen, grounded with a mortar and then the test item was filled into the apparatus.
The vapour pressure was measured in the temperature range of 55 °C to 125 °C in intervals of 10 K and 5 K, respectively.
Description of key information

Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °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.
