Frequently Asked Questions

Q: What are the primary applications of Hollow Glass Microspheres in the mining and coatings industry?

They are widely used in anti-corrosion coatings, oilfield cementing operations, syntactic foams for deep-sea exploration, and lightweight building materials to improve thermal insulation and reduce weight.

Q: How do these microspheres improve the performance of syntactic foams?

By providing a low-density core with high compressive strength, they allow the foam to withstand extreme underwater pressures while remaining buoyant.

Q: Can the particle size be customized for specific industrial needs?

Yes, while common sizes range from 2-130 µm, we accept customization requests to meet specific D50 and D90 requirements for your unique application.

Q: Are these microspheres resistant to harsh chemical environments?

Absolutely. Due to their alkali-lime borosilicate glass composition, they exhibit excellent stability and resistance to both acids and alkalis.

Q: How does the floatation rate impact the quality of the product?

A floatation rate of ≥ 95% indicates a high percentage of intact hollow spheres, ensuring the promised low density and consistent buoyancy in the final mixture.

Q: Which other non-metallic minerals are often used alongside these microspheres?

They are frequently used in conjunction with Calcium Carbonate, Talc Powder, and Mica Powder to create complex composite materials with specific mechanical and thermal properties.
