3M Hollow Glass Beads

3M™ Glass Bubbles are hollow, water-resistant, and chemically-stable soda-lime-borosilicate glass microspheres that are engineered to serve as an alternative to conventional fillers and additives like silica, calcium carbonate, talc, and clay. These low-density particles are used in a wide range of industries to help reduce part weight, lower costs, and enhance product properties. Because of their unique spherical shape, they also offer a number of important benefits, including higher filler-loading, lower viscosity/improved flow, and reduce shrinkage/warpage. Discover how 3M™ Glass Bubbles can be mixed in with a variety of compounds to be sprayed, cast, and/or moulded with incredible results.
