Hollow glass microspheres made from water-resistant and chemically-stable soda-lime borosilicate glass, 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.
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, hollow glass microspheres are a superior alternative to many conventional fillers and additives such as silica, calcium carbonate, talc and clay.
