Product DETAILS SAMPLE

The lightweight filler

The start to a better finish

3M™ Glass Bubbles for density reduction, solar reflectivity and more.

Product Overview

3M Glass Bubbles 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 3M Glass Bubbles blend readily into compounds and makes them adaptable to a variety of production processes including spraying, casting and molding.

The chemically stable soda-lime-borosilicate glass composition of 3M Glass Bubbles provides excellent water resistance to create more stable emulsions. They are also non-combustible and nonporous, so they do not absorb resin. And, their low alkalinity gives 3M Glass Bubbles compatibility with most resins, stable viscosity and long shelf life.
