The appearance of hollow microspheres is gray white, which is a loose and flowable powder material. The characteristics of gray white hollow glass microspheres are: sound insulation, flame retardancy, good electrical insulation, low density, low oil absorption, and high strength. Widely used in inks, adhesives, engineering plastics, modified rubber, and electrical insulation components. Due to its stable performance, good weather resistance, and low price, it has been widely used.
The main components of hollow microspheres are silicon dioxide SiO2 and aluminum oxide Al2O3, which are sintered and sorted at 1400 ºC. The diameter is between 5-1000 microns, and the larger the diameter, the higher the hollow rate. Conversely, the smaller the diameter
Hollow microspheres have a grayish white or pure white appearance and are a loose, flowable inorganic non-metallic powder material. Hollow glass beads are characterized by good sound insulation, flame retardancy, electrical insulation, low density, low oil absorption, low thermal conductivity, good dispersibility and fluidity, high chemical stability, and high compressive strength. Widely used as high-quality filler for insulation coatings, adhesives, engineering plastics, modified rubber, electrical insulation components, fiberglass, SMC, artificial stone and other products. Due to its stable performance and good weather resistance, it has been widely used.
