    3M™ Glass Bubbles K20 have a density of 0.2 g/cc and an isostatic crush strength of 500 psi.

    3M glass bubbles K20 are used extensively in shallow water buoyancy applications. Their low density (0.20 g/cc) provides reliable buoyancy, and their high isostatic strength makes them an ideal choice when processing or buoy depth requires more strength. And, like all 3M glass bubbles, K20 bubbles are compatible with thermoset resins like polyurethane and epoxy, and are virtually insoluble in water.
