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.
Foamed polyurethane (FPU) is a soft polyurethane foam containing 90 % of air by volume. It is used as cushioning and supporting material, and as elastic additive to the goods and insulation. Because of its fine-meshed structure the polyurethane foam is characterized by good elasticity and air permeability.
