3M™ Glass Bubbles A16/500 have a density of 0.16 g/cc and an isostatic crush strength of 500 psi. They have less than 1% sinkers ( >1.0 g/cc density particles) by volume and are surface treated to be compatible with buoyancy module manufacturing. Like other 3M™ Glass Bubbles in our floated product series, this product is ideal for use in a number of aerospace and oil and gas applications.
Higher filler loading
The benefits don't end there; although 3M glass bubbles A16/500 have thin walls, they have good isostatic crush strength of 500 psi, meaning they can survive both the rigorous demands of processing and water pressure at depth. A16/500 bubbles have a fractional survival rate of 80% or more, at 500 psi for consistent performance and greater survivability. The unique spherical shape of these bubbles offers a number of important benefits, including: higher filler loading, lower viscosity/improved flow and reduced shrinkage and warpage. Adding to this product's versatility is its ability to be easily blended into compounds, making it adaptable to a variety of production processes including spraying, casting and molding.
Aerospace Void Filler
3M glass bubbles A16/500 can be used for many applications including aerospace void filler. Airplanes are constructed with many types of lightweight, honeycomb composite structures and panels. Our A16/500 glass bubbles are used to make these parts, especially when it is necessary to create lightweight, functional and strong parts that can stand up to the rigors of air travel.
What are 3M Glass Bubbles?
Our 3M glass bubbles are engineered hollow glass microspheres that are alternatives to conventional fillers and additives such as silica, calcium carbonate, talc and clay. These low-density particles are used in a wide range of industries for many demanding applications to reduce part weight, lower costs and enhance product properties.

The 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. Additionally, the spherical shape helps the glass bubbles readily blend into compounds, making them adaptable to a variety of production processes, including spraying, casting and molding. They also offer greater survivability under demanding processing conditions, such as extrusion, injection molding and other high shear mixing processes.
The chemically stable soda-lime-borosilicate glass composition of 3M glass bubbles provides excellent water resistance. These bubbles are non-combustible and non-porous, so they do not absorb resin; and their low alkalinity gives 3M glass bubbles compatibility with most resins, stable viscosity and long shelf life.
