Vapour pressure:
< 0.001 Pa

Any other information on results incl. tables

The weight loss of the test substance at 110°C, 120°C, 130°C and 140°C was lower than the weight loss of hexachlorobenzene at the same temperatures. From this, it was concluded that the vapour pressure of the test substance is < 1.47 x10 -3Pa = < 1.10 x 10-5mm Hg.

 

Applicant's summary and conclusion

Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of Aquapel® 203. The vapour pressure of the test substance at 20°C (293K) was < 1.47 x 10-3 Pa = < 1.10 x 10-5 mm Hg.
