Hollow glass microspheres are a ultra-lightweight, inorganic, non-metallic, hollow alternative to conventional fillers and additives. They find applications in many demanding industries such as paints, coatings, adhesives, sealants, cast polyester, compounding and many more. The low-density material is used to reduce weight, lower costs and enhance product properties.

The unique spherical shape of the hollow glass microspheres offer a number of important benefits, including higher filler loading, lower viscosity and reduced shrinkage. It further makes it more adaptable to a variety of production processes including spraying, casting and molding.

The chemically stable soda-lime-borosilicate glass composition provides excellent water resistance to create more stable emulsions. They are non-combustible and non-porous, so they do not absorb resin. The hollow glass microspheres also create stable voids, which result in low thermal conductivity and low dielectric constant.

Hollow glass microspheres are available in a variety of sizes and grades to help you meet your product and processing requirements.
