Bauspot GB22 (Glass Bubbles)
Bauspot GB22 are Glass Bubbles S22 produced by 3M company.
They specifically are hollow glass spheres with a typical density of 0.22 g/cc and an isostatic crush strength of 400 psi. These glass bubbles can be used in a variety of applications including oil and gas drilling and tooling board. The bubbles produce strong, stable voids and low thermal conductivity, helping the coating achieve the necessary compressive strength.
Price range: 4,35 € through 29,20 €
Bauspot GB22 Glass Bubbles are manufactured by 3M™ and most particularly are engineered hollow glass microspheres made from water-resistant and chemically-stable soda-lime borosilicate glass. Additionally, they are non-combustible and non-porous, so they do not absorb resin; and their low alkalinity makes them compatible with most resins while providing a stable viscosity and a long shelf life.
These low density particles are used for many demanding applications across a wide range of industries to provide temperature and pressure resistance, reduce part weight, lower costs and enhance overall product properties. For these reasons, they are a superior alternative to many conventional fillers and additives such as silica, calcium carbonate, talc and clay.
