The inside of hollow glass beads is thin gas, so it has the characteristics of sound insulation and heat insulation. It is an excellent filler for various heat preservation and sound insulation products. The thermal insulation properties of hollow glass microspheres can also be used to protect products from thermal shocks caused by alternate changes between rapid heating and rapid cooling conditions. The high specific resistance and extremely low water absorption make it widely used in the processing and production of cable insulation materials. Hollow glass beads have been widely used in artificial agate, marble, glass fiber reinforced plastic bowling and other compatible materials and high-end thermal insulation coatings, which have significantly reduced product weight and good thermal insulation effects. Hollow glass beads are sensitizers with excellent performance of civil emulsion explosives, which can significantly improve the initiation performance of emulsion explosives and extend the storage period. In addition, hollow glass beads can also be used in putty to increase the volume, improve the polishing performance, and improve the acid and alkali resistance.
