Frequently Asked Questions

Q: What are the primary advantages of solid glass microspheres over hollow ones?

Solid glass microspheres offer significantly higher density and crushing strength, making them ideal for abrasive media and high-load composite materials where structural integrity is critical.

Q: Can you provide customized mesh sizes for specific industrial needs?

Yes, we accept full customization. While we offer standard sizes from 20 mesh to 320 mesh, we can tailor the particle size distribution to match your exact technical requirements.

Q: In which non-metallic mineral applications are these beads used?

They are widely used as fillers in polymer composites, as polishing media in mineral processing, and as reflective elements in specialized industrial coatings.

Q: How do these microspheres perform under high-temperature conditions?

Our solid glass beads are engineered with a low thermal expansion coefficient and high heat resistance, ensuring they remain stable and do not deform during thermal processing.

Q: Are these products suitable for use in chemical-heavy environments?

Absolutely. Due to their excellent chemical stability, they are highly resistant to a wide range of acids and alkalis, making them ideal for protective industrial paints.

Q: What makes your manufacturing process "trusted" for coating partners?

We combine advanced non-metallic mineral extraction expertise with precision glass manufacturing, ensuring consistent purity and sphericity across every shipment.
