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, also known as Urethane Foam, Foam Rubber, PU, PUF and PUR, is a flexible, open-cell type of foam that has a near-infinite amount of applications due to the following characteristics: 1  Compressibility.2  Cushioning.3  Energy absorption.4  Fabricatibility.olyurethane foam, also known as Urethane Foam, Foam Rubber, PU, PUF and PUR, is a flexible, open-cell type of foam that has a near-infinite amount of applications due to the following characteristics: 1  Compressibility. 2  Cushioning. 3  Energy absorption. 4  Fabricatibility.
