3Mâ„¢ Glass Bubbles iM30K are 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, or other vigorous processing equipment (e.g. Banbury mixers, etc.), offering improved processing over many conventional fillers.
