Hollow glass microspheres（Hollow glass microspheres） are special processed glass microspheres. The main characteristics of hollow glass microspheres are smaller density and worse thermal conductivity than glass microspheres. It is a new type of micron light material developed in the 1950s and 1960s. Its main component is borosilicate, with a particle size of 10-250 microns and a wall thickness of 1-2 microns. Hollow glass beads have the characteristics of high compressive strength, high melting point, high resistivity, low thermal conductivity and thermal shrinkage coefficient, and are known as the 21st century. "Material for Space Age". Hollow glass microspheres have obvious effects of weight reduction and sound insulation, which make the products have good crack resistance and reprocessing performance. They are widely used in glass fiber reinforced plastics, artificial marble, artificial agate and other composite materials, as well as in the fields of petroleum industry, aerospace, new high-speed train, automobile and ship, thermal insulation coating, etc. Domain has greatly promoted the development of science and technology in China.
Widely used in FRP products, composite foam plastics, artificial marble, synthetic wood, sound insulation and insulation materials, atomic ash, deep-sea buoyancy materials, bowling balls, low-density adhesives, sealing materials, light resin handicraft, mural wall frame, wall sandwich layer structure, light packaging materials in electronic industry, microwave absorption. Materials, lightweight concrete, emulsified explosives, etc.
