Conclusions:
The vapour pressure of ZMB2 has been predicted to be 1.87E-011 at 25 ºC using the EPIWIN MPBPVP model.

Description of key information

The vapour pressure of ZMB2, predicted using the EPIWIN MPBPVP v1.43 model, is 1.87E-011 Pa at 25 ºC.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The key value should read < 1.87E-09 as it is not posisble to add a vapour pressure which is as low as that of ZMB2.

The vapour pressure of ZMB2, predicted using the EPIWIN MPBPVP v1.43 model, is 1.87E-011 Pa at 25 ºC.
