These additives are 40 percent stronger than 3M's previous leading high strength glass bubbles and, at 17 microns, are approximately half their size. 3M™ Glass Bubbles iM30K have a density of 0.6 g/cc and an isostatic crush strength of 28,000 psi.
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 processing equipment (e.g., Banbury mixers, etc.), offering improved processing over many conventional fillers.
