Details

3M™ Glass Bubbles K25 have a density of 0.25 g/cc and an isostatic crush strength of 750 psi. The general purpose K Series glass bubbles are the most economical 3M glass bubbles.

Low density (0.25 g/cc) and high isostatic strength make 3M glass bubbles K25 ideal additives for shallow water buoyancy applications or processing applications where high strength is needed. In addition, like all 3M glass bubbles, K25 bubbles are compatible with thermoset resins like polyurethane and epoxy, and are virtually insoluble in water.
