S60HS glass bubbles have a density of 0.6 g/cc and an isostatic crush strength of 18000 psi. Average particle size is 30 microns.
3M™ Glass Bubbles S60HS are new, high-strength polymer additives made from a water-resistant and chemically-stable soda-lime-borosilicate glass. These hollow glass microspheres can be used as a low density filler material ideal for plastic and rubber parts created from injection molding, extrusion processes, and/or other vigorous procession equipment (Branbury mixers, etc.).
3M glass bubbles help to reduce weight, reduce noise, vibration, and harmonics; reduce thermal expansion; and contribute to cost savings. They are ideal additive materials in the automotive, truck, rail and aerospace industries.
