Lightweight hollow glass microspheres are tiny, hollow spheres made of glass. They are typically less than 100 microns in diameter and have a low density, which makes them an attractive material for a wide range of applications.
One of the main advantages of hollow glass microspheres is their low density. Because they are hollow, they have a much lower weight than solid glass particles of the same size. This property makes them ideal for use in lightweight composite materials. HGMs can be added to polymers, resins, and other materials to improve their strength and reduce their weight.
Hollow glass microspheres are also used as a filler in many products, including adhesives, coatings, and sealants. Their small size and low density allow them to be easily mixed into these materials, improving their properties and reducing their overall weight.
In addition to their use in composites and fillers, hollow glass microspheres have a range of other applications. They can be used as insulation in building materials, as a proppant in oil and gas drilling, and as a reflective material in coatings and paints.
