Hollow glass microspheres represent a revolutionary multifunctional filling material, characterized by their ultra-fine, hollow, spherical shapes.
These microspheres exhibit a distinctive gray-white or light gray hue. Comprised primarily of silicon dioxide and alumina, they offer a bulk density
ranging from 0.9 to 1.2 grams per cubic centimeter, with a true density standing at 1.7 grams per cubic centimeter. The particle size of these
spheres varies between 44 to 2.6 microns, available in classifications such as 325 mesh, 500 mesh, 800 mesh, 1250 mesh, 2500 mesh, and 5000
mesh. With a sphericity exceeding 95%, they boast a robust outer shell filled with inert gases like nitrogen dioxide and carbon dioxide.
Our material offers impressive pressure resistance strength, ranging from 4000 to 7000 MPa, alongside excellent wear resistance and a remarkable
fire resistance surpassing 1450 degrees. Its outstanding chemical stability ensures resilience against common acid, alkali, and salt solutions.
Moreover, it provides superior sound and heat insulation, with a thermal conductivity coefficient of 0.10 to 0.12.
Our product range allows for customization of special particle sizes to meet specific needs.
