Hollow glass microspheres are micrometer-sized hollow glass microspheres with smooth surfaces. The main chemical component is soda-lime borosilicate glass. They appear as hollow transparent spheres under a microscope.
Hollow glass microspheres have multiple properties such as low density, high strength, low thermal conductivity, electrical insulation, high temperature resistance, acid and alkali resistance, good fluidity and chemical stability. They are multifunctional cutting-edge new materials across fields.

Application
Hollow glass microspheres are a lightweight, high-strength material with a variety of excellent properties, so they are widely used in many fields. The main applications include: engineering plastics, rubber, coatings, paints, building materials, buoyancy materials, oil fields, aerospace, 5G communications, automobiles, ships, etc.
Specific application areas are as follows:
Engineering plastics and rubber:
Hollow glass microspheres can reduce the density of plastics and rubbers, improve the strength and stiffness of materials, and reduce costs.
Coatings and paints:
Hollow glass microspheres can improve the rheological properties of coatings, improve the thermal insulation, sound insulation, wear resistance and other properties of coatings, and reduce the VOC (volatile organic compound) content of coatings.
Building materials:
Hollow glass microspheres can be used to produce lightweight and heat-insulating building materials, such as insulation boards, lightweight mortars, etc.
Buoyancy materials:
Due to their low density characteristics, hollow glass microspheres are widely used in deep-sea buoyancy materials, life-saving equipment, etc.
Oilfield:
Hollow glass microspheres can be used to improve the performance of drilling fluids, reduce drilling costs, and play a role in cementing and fracturing operations in oil fields.
