3M™ Glass Bubbles S32X

3M™ Glass Bubbles S32X have a density of 0.32 g/cm³ and isostatic crush strength resistance od 2000 psi / 138 bar. They are engineered hollow glass microsphere used to reduce the density of syntactic foam blocks for subsea buoyancy modules.

3M™ Glass Bubbles S32X are ideal additives for shallow water buoyancy application or processing application where strength is needed. Like all 3M glass bubbles S32 glass bubbles are compatible with thermoset resins like polyurethane and epoxy polymers and they are virtually insoluble in water or oil.
