We offer 3M Hollow Glass Microspheres for Thermal Insulation Applications. The high strength and low thermal conductivity (0.06 – 0.2 W•m-1•K-1 at 0°C)* of 3M™ Glass Bubbles make them ideal additives in pipeline and riser insulation. These inert particles are completely compatible with all other components of the insulating system, including polyurethane, polypropylene and epoxy. What''s more, these hollow glass microspheres are virtually insoluble in water…providing better utility in underwater applications.

Typical application area where Thermal Conductivity can be reduced: -

PVC Window Profiles & Frames
Insulation Profiles
Solar Reflective Paints

GEOSPHERES are Spherical Ceramic Microsphere are unique gray in colored, finer particle size, very high-strength They are opaque to visible light, but transparent to UV light. GEOSPHERES are used to reduce VOC levels, increase filler loadings, improve hardness, and add burnish, scrub and abrasion resistance to a variety of coating formulations. Due to their low resin demand, high hardness and inert chemistry, these products have found utility in high solids, water reducible radiation curbale and high durability coatings, powder coatings, and a wide range of premium performance coatings. GEOSPHEREs are Ceramic Microsphers are best dispersed by using sand, ball and roller mills. For optimal dispersion, the GEOSPHERES should be added to the grinding, along with other filler materials. Use of a proper Wetting and dispersant can help in the wet-out and dispersion.

3M™ Glass Bubbles S28HS are hollow glass spheres with a typical density of 0.28 g/cc and an isostatic crush strength of 3,000 psi. These glass bubbles are designed for numerous applications such as deep water syntactic foams and airless spray coatings. The bubbles produce strong, stable voids with low thermal conductivity, helping the coating achieve the necessary compressive strength.
3M™ Glass Bubbles S28HS are engineered hollow glass spheres made from water-resistant and chemically-stable soda-lime borosilicate glass. Like all 3M™ Glass Bubbles, our S28HS glass bubbles are water and oil resistant, providing better utility in underwater applications. Additionally, they are non-combustible and non-porous, so they do not absorb resin; and their low alkalinity makes this product compatible with most resins while providing a stable viscosity and a long shelf life.

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.
