3M™ Glass Bubbles HGS Series, HGS4K28, 507 lb (230 kg), 4 ft (1.2 m) Semi-bulk Bag by 3M

3M™ Glass Bubbles HGS Series are a density-reducing agent for drilling, completion, work-over fluids, and cement slurries. These bubbles can help reduce control-fluid density, enhance homogeneous control-fluid properties, and eliminate the need for specialized equipment used in foamed cement. Help minimize problems with excellence overbalance conditions with 3M™ Glass Bubbles HGS Series.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.
