Frequently Asked Questions
Q: What are the primary benefits of using hollow glass microspheres in coatings?
They provide significant weight reduction, enhance thermal insulation, and improve the volumetric solids content of coatings without increasing the density.
Q: How do these microspheres perform in oilfield cementing?
Their low density allows for the creation of lightweight slurries that prevent formation fracture while maintaining high compressive strength.
Q: Can you customize the particle size for specific industrial needs?
Yes, while common sizes range from 2-130 µm, we accept customization requests to meet your specific project requirements.
Q: Are they compatible with epoxy and resin systems?
Absolutely. Their chemical stability and spherical shape make them ideal fillers for epoxy resins, synthetic rubbers, and various adhesives.
Q: What makes borosilicate glass superior to other glass types for this product?
Borosilicate glass offers significantly higher thermal shock resistance and better chemical durability against corrosive agents.
Q: How is the floatation rate measured and why is it important?
The floatation rate (≥95%) indicates the percentage of intact hollow spheres. A high rate ensures consistent low density and insulation properties.
