Conclusions:
According to EU A.4 test method, the saturated vapour pressure of Eversorb EP4 were 0.055 kPa at 20.0°C, 0.078 kPa at 25.0°C, 0.194 kPa at 40.0°C and 0.374 kPa at 50.0°C.
Executive summary:

The vapour pressure of Eversorb EP4 was determined according to EC REGULATION No 761/2009 Annex I A.4 Vapour pressure. Therefore, the saturated vapour pressure of Eversorb EP4 were 0.055 kPa at 20.0°C, 0.078 kPa at 25.0°C, 0.194 kPa at 40.0°C and 0.374 kPa at 50.0°C.

Description of key information

The saturated vapour pressure of Eversorb EP4 was 0.078 kPa at 25.0°C (EC A.4).

Key value for chemical safety assessment

Vapour pressure:
