3Mâ„¢ Glass Bubbles K15 are engineered hollow glass microspheres that are alternatives to conventional fillers and additives such as silicas, calcium carbonate, talc, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties. The unique spherical shape of 3M glass bubbles offers a number of important benefits, including: higher filler loading, lower viscosity/improved flow and reduced shrinkage and warpage. It also helps the 3Mâ„¢ Glass Bubbles K15 blend readily into compounds and makes them adaptable to a variety of production processes including spraying, casting and molding.
