Product Details

3M™ Glass Bubbles S32 have a density of 0.32 g/cm3 and an isostatic crush strength of 2000 psi / 138 bar. The S Series glass bubbles have smaller particle sizes than the K Series.

3M™ Glass Bubbles S32 are ideal additives for shallow water buoyancy application or processing application where strenght 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.
