About this product
Product information from the supplier.
Low-Density Hollow Glass Microspheres are advanced micro-scale hollow particles composed primarily of alkali-lime borosilicate glass. Featuring a high-gloss surface and a unique cellular structure, these spheres provide an exceptional balance of low density and high mechanical strength, making them indispensable for high-performance industrial applications where weight reduction and structural integrity are critical.
Engineered for versatility, these microspheres deliver outstanding thermal conductivity, superior electrical insulation, and remarkable resistance to high temperatures, acids, and alkalis. Their excellent chemical stability and fluidity allow for seamless integration into adhesives, anti-corrosion coatings, oilfield cementing, and lightweight transportation vehicles, enhancing the efficiency and durability of end products.
