About this product
Product information from the supplier.
Product Overview
Our Low-Density Hollow Glass Microspheres are high-performance, micro-scale hollow particles composed of alkali-lime borosilicate glass. Featuring a brilliant shiny surface and an engineered internal void, these microspheres provide a critical balance of ultra-low density and high mechanical strength, making them indispensable for advanced industrial lightweighting.
Engineered for versatility, these spheres offer exceptional thermal insulation, outstanding electrical resistivity, and superior resistance to acids, alkalis, and high temperatures. They are widely integrated into syntactic foams, anti-corrosion coatings, oilfield cementing, and lightweight transportation components to optimize material efficiency and structural performance.

Frequently Asked Questions
Q: What are the primary benefits of using hollow glass microspheres in coatings?
They provide significant weight reduction, improve thermal insulation, and enhance the anti-corrosion properties of the coating while maintaining high mechanical strength.
Q: Can these microspheres be customized for specific particle sizes?
Yes, while common sizes range from 2-130 µm, we accept customization requests to match your specific technical requirements.
Q: How do these spheres perform in oilfield cementing operations?
Their low density and high compressive strength allow for the creation of lightweight cements that reduce hydrostatic pressure on the formation without losing structural integrity.
Q: Are hollow glass microspheres chemically stable?
Yes, they are made from alkali-lime borosilicate glass, which provides excellent stability and resistance to most acids and alkalis.
Q: What is the difference between true density and bulk density in these products?
True density refers to the density of the material itself (including the hollow core), while bulk density includes the air space between the particles in a container.
Q: Which industries benefit most from these low-density materials?
Industries focusing on lightweight transportation, aerospace, high-end construction (energy saving), and marine syntactic foams benefit the most.
