3M™ Glass Bubbles for Buoyancy
3M™ Glass Bubbles have pressure ratings ranging from 250 psi to 18,000 psi and densities ranging from 0.125 g/cc to 0.6 g/cc. When made into syntactic foams, they can be used in buoyancy modules, buoys, moorings, or undersea vehicles.
In addition, unlike some competing products, 3M™ Glass Bubbles are virtually insoluble in water…providing better utility in underwater applications.
