3M™ Glass Bubbles S28HS, 1 gal, Sample
- Part Number S28HS
- 3M ID WF600914916
Details
Highlights
- Decreases weight and increases buoyancy for lower density in finished parts
- Versatile use – adaptable to a variety of production processes including high shear liquid mixing systems
- Delivers stable voids for reduced thermal conductivity and dielectric constant in syntactic foams
- Provides excellent water and oil resistance for use in underwater applications
- Very good strength-to-density ratio for use in a variety of construction and oil and gas applications
- Good choice for dead-pressing resistant emulsion explosives
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.
What are 3M™ Glass Bubbles?
Our 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.
Superb Strength-to-Weight Ratio
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.
Airless Spray Coatings
3M glass bubbles S28HS bubbles can be used in many applications. One area where they excel is in airless spray
