<div>They don't say much about the manufacturing process. This could contain micropheres as a filler. I tend to take Alan's point on this from a safety perspective.</div><div><br></div><div>Don't get me wrong, I would love to have a low cost alternative to syntactic foam. It just that this is such a safety critical item on a manned submersible. Lets say we use a non syntactic foam for buoyancy, get the boat neutral by flooding MBT and start the dive over a deep trench. Captain has a heart attach because it just so beautiful out the viewport. With any shrinkage at all of the foam, the boat would go slightly negative and boat would eventually crush unless their were automatic systems on board. I am just saying if it were my boat, I would do some testing before putting my life and the life in the hands of a product that was not specifically designed for this application or unless I confirmed that it would not shrink by testing. What you are planning on using may be perfectly fine. It just seems prudent to do some testing.</div><div><br></div><div>Best Regards</div><div><br></div><div>Cliff</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div>

Then, when it is brought up the check valve keeps the pressure at the max depth pressure (600' depth) . When the pipe is at the surface it would still have the pressure of say 300psi.

<div>Brian, this is not syntactic foam. It's made for marine service but not for deep submergence. It is really for surface buoyancy. I would not use this if you are relying on it for buoyancy at depth. It is the macro-spheres and microspheres in syntactic foam that prevent it compression at depth. I don't think this foam has either.</div><div><br clear="none"></div><div>Best Regards</div><div><br clear="none"></div><div>Cliff</div><div><br clear="none"></div><div><br clear="none"></div>

<div>Brian, I have been tied up and have not had a chance to follow this thread but I wanted to make sure you understand that unless this pour-able 2 part foam has a filler like 3-M's glass micro-spheres or some kind of incompressible macrosphere, then while the foam may appear rigid, it would compress when subjected to deep water and thus your buoyancy would be reduced. I don't think this is a replacement for syntactic foam if that is what you are doing. Can you send a link to the foam you are using?</div><div><br clear="none"></div><div>Best Regards </div><div><br clear="none"></div>

This pouring of the foam is not going to be as straight forward as I thought, The barrier to contain the foam is working out good, I'm just using wood and thin 1/8" luan , then I'm covering that with 4 mil flexible plastic ( heavy garbage type bag) so the foam won't stick to it. But I'm worried that any little gaps I have and the liquid foam might run out the bottom of those areas before it starts foaming, so I'm cramming big blankets ( cheap moving blankets from harbor freight) in tight to contain any foam.
