I was wondering, what are the advantages of using Sub sea buoyancy foam for buoyancy? What are alternative cheaper methods for buoyancy?
Hi @NIW,
The subsea buoyancy foam that we offer is designed not to absorb water, even at relatively high pressures. We’ve tested a lot of other foams and almost all of them absorb a significant amount of water under pressure, which means that they get heavier and you lose buoyancy.
If you’re not going too deep, like 10-20m, then there may be other options that would work.
If you’re going much deeper, like 300+ meters, then our foam will start to absorb water and you’d have to look at higher performance alternatives like syntactic foam.

Hi Rusty, quick question: I was comparing the specs on General Plastics’ website with the depth ratings of the Buoyancy Foam listed on your site, and they seem a bit different. I was wondering—did your team run separate tests, or are their ratings just more conservative? Thanks so much!
Hi @Tides -
Blue Robotic conducted testing on the buoyancy foam purchased from General Plastics, and based on its performance, increased the depth rating to what is listed in the Technical Details section of the relevant product pages. I hope that answers your question!
