3M™ Glass Bubbles K37 glass bubbles have a density of 0.37 g/cm3 and an isostatic crush strength of 3000 psi / 207 bar

3M™ Glass Bubbles K37 are high-strength polymer additives made from a water-resistant and chemically-stable soda-limeborosilicate glass. These hollow glass microspheres can be used as a low-density filler material that is ideal for plastic and rubber parts created from compression molding, extrusion processes and/ or other vigorous processing equipment.
