Hereâs what you can expect: 1  First, a speculum is placed in the vagina, just like for a Pap. The cervix is cleaned off with a soap solution.Then a soft flexible tube, thinner than the inside of a pen, is passed into the uterus. 2  The speculum is removed and the ultrasound probe inserted.
You will likely have similar results. Closed cell polyurethane foam will only absorb water if the individual cells are damaged, which CAN happen over time, but the causes of wet foam in boats isn't all that clear. It is likely that freeze cycles will gradually cause foam deterioration.
Polyurethane foam insulation is mixed with water, then sprayed under pressure from a pneumatic pump. As it mixes with oxygen from the air and the water dries, the foam expands, then hardens and cures within a few minutes. The volume of dry spray foam is five to ten times greater than that of wet spray foam.
