3M™ Glass Bubbles make spackling, engineered wood and other building materials lighter weight and easier to work with.
Used as density-reducing additives, these hollow glass microspheres help create building materials that are versatile, lightweight and easy to work with. Their low density enables higher filler loading, as well as a lower cost per volume compared to many conventional fillers. Because of their spherical shape, 3M™ glass bubbles behave like tiny ball bearings, easily rolling over one another. This can help improve the flow of many materials to which they are added. 3M glass bubbles can also help improve sandability and reduce shrinkage and warpage in spackling compounds, wood composites and other materials – helping reduce rework.
3M glass bubbles are engineered to withstand the high temperatures and stresses of processing conditions such as liquid phase polymer processing, high-viscosity melt compounding and high-pressure injection molding. Potential applications include:
In addition, 3M glass bubbles can be formulated into a variety of paints and specialty coatings, including solar reflective roof coatings.
3M glass bubbles can be used to create polymer/wood composites that behave more like natural wood. By providing greater void volume, 3M glass bubbles make it easier for nails and screws to penetrate the typically dense polymer. The low thermal conductivity of 3M glass bubbles can also enable composites that retain the warm feel of natural wood.
