3M™ Glass Bubbles K37 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 that is ideal for plastic and rubber parts created from compression molding, extrusion processes, and/or other vigorous processing equipment. 3M glass bubbles help to reduce weight, reduce noise, vibration and harmonics, reduce thermal expansion, and contribute to cost savings. They are used in a variety of applications in diverse markets, including automotive, construction materials, electronics, marine and paints and coatings.
