3M glass bubbles are a superior alternative to many conventional fillers and additives such as silicas, calcium carbonate, talc, clay and other materials used in demanding applications. Our low-density spheres are used in a wide range of industries to reduce part weight, lower costs and enhance product properties – making them more reliable and affordable.
The benefits don’t end there; although these hollow spheres have thin walls, they have an impressive isostatic crush strength of 3,000 psi, making them suitable for a number of buoyancy applications, including additives in buoys and moorings. S28HS bubbles have a fractional survival rate of 90%, at 3,000 psi for consistent performance and greater survivability.
Notably, 3M™ Glass Bubbles S28HS are lower density 3,000 psi glass bubbles that offer significantly less weight, for better thermal conductivity at a given depth rating. These glass bubbles provide significantly lower density for better thermal conductivity at a given depth rating compared with S35 glass bubbles.
3M glass bubbles S28HS bubbles can be used in many applications. One area where they excel is in airless spray coatings. Here’s how it works – an airless spray pumps a liquid that shoots through a nozzle. When bubbles are added to a coating, they have to survive this process and remain intact, meaning it’s important to pick bubbles on the basis of strength. Our bubbles offer sufficient strength at a minimal density.
In general most of airless spray equipment is in the 2,500-4,000 psi range. Our S28HS may work well for airless spray depending upon the formulation. It’s not just the fact that it has a 3,000 psi rating, this bubble has an average diameter of 30 microns, and 0.28 g/cc density. This unique combination of strength, overall particle size and density means this bubble may be well suited for airless spray coatings.
