About this product
Product information from the supplier.
Our Low-Density Hollow Glass Microspheres are premium, micro-scale engineered particles crafted from alkali-lime borosilicate glass. Featuring a precision-engineered internal void and a brilliant shiny surface, these microspheres deliver an optimal equilibrium between ultra-low density and high mechanical strength. This unique architecture makes them a critical component for advanced industrial lightweighting and high-performance material engineering.
Designed for maximum versatility, these spheres offer exceptional thermal insulation, superior electrical resistivity, and robust resistance to acids, alkalis, and extreme temperatures. They are widely utilized in the production of syntactic foams, anti-corrosion coatings, oilfield cementing, and lightweight transportation components to significantly enhance structural performance and material efficiency.

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 anti-corrosion properties 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 lightweight cements that reduce hydrostatic pressure 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 particles in a container.
Q: Which industries benefit most from these low-density materials?
Industries focusing on lightweight transportation, aerospace, energy-saving construction, and marine syntactic foams benefit the most.
