Hollow glass microspheres are small spherical powders that are hollow and contain inert gases. They belong to non-metallic inorganic materials and are known as "materials of the space age". They have been widely used in building materials, plastics, rubber, coatings, petrochemicals, metallurgy, deep-sea and aerospace industries, especially in the petroleum cementing industry, and have irreplaceable important applications. With the further recognition of the unique properties of hollow glass microspheres, their application fields will continue to expand.
Our company's glass beads have been exported to various parts of the world, including Singapore, India, Russia, Laos, the United Kingdom, and the United States.
