Product Description

Discover the revolutionary Hollow Glass Microspheres, a state-of-the-art multifunctional filling material, characterized by its ultra-fine and perfectly spherical hollow shape.
These microspheres glisten in shades of gray-white or light gray, composed primarily of silicon dioxide and alumina, offering a bulk density
ranging from 0.9 to 1.2 grams per cubic centimeter and an impressive true density of 1.7 grams per cubic centimeter. The delicate particle size
of these spheres spans from 44 to 2.6 microns, available in a range of mesh sizes: 325, 500, 800, 1250, 2500, and 5000 mesh, ensuring versatility,
and boasting a remarkable sphericity of over 95%. Encased in a robust outer shell, these spheres are filled with inert gases, including nitrogen and
carbon dioxide, endowing them with exceptional pressure resistance (4000-7000 MPa) and superior wear resistance.
These microspheres withstand high temperatures with fire resistance exceeding 1450 degrees, offering exceptional chemical stability, impervious to
common acids, alkalis, and salt solutions. They are also engineered for sound and heat insulation, featuring a thermal conductivity coefficient
ranging from 0.10 to 0.12, making them an ideal insulating material.

Customizable particle sizes available to meet your specific needs.

Experience the unparalleled compressive strength of hollow glass microspheres, engineered for superior performance.
When seamlessly integrated into composite materials, they exhibit the following transformative functions and characteristics:

1: Enhance structural integrity and optimize performance: Unlike conventional fillers, which can introduce soft or uneven particles causing wear,
hollow glass microspheres offer exceptional fineness, dramatically boosting scratch resistance and diminishing the friction coefficient.
This results in a marked improvement across various performance parameters.
2: Economical efficiency: Boasting the lowest oil absorption rate at 15-18%, significantly less than talc or calcium carbonate, these microspheres
when used as fillers, minimally impact the material's impact toughness, allowing for addition in large proportions, up to 70%.
Their excellent flowability permits formation in small molds without heating or pressure, simplifying the manufacturing process,
and slashing product costs.
