Yes, their low density and high compressive strength make them ideal for lightweight cementing, reducing the hydrostatic pressure on the formation.
Due to their minimal thermal conductivity and reflective surface, they create a thermal barrier that reduces heat transfer in buildings and industrial equipment.
Common sizes range from 2 to 130 µm, but we provide professional customization to meet specific industrial requirements.
Absolutely. Their spherical shape and chemical stability make them excellent fillers for adhesives, improving fluidity and reducing density.
Borosilicate glass provides superior heat resistance, higher chemical stability, and better mechanical strength compared to standard alkali-lime glass.
Talc powder for plastic compounds that improves dimensional stability, heat resistance, and reduces shrinkage. Enhances mechanical properties and processing characteristics in various polymer applications.
Sintered colored sand, also known as high-temperature sintered colored sand or ceramic colored sand, is a high-end decorative material that uses a high-temperature ceramic sintering process to color selected quartz sand. Its core lies in using high temperatures (usually above 800℃) to fuse inorganic ceramic glazes with the surface of the quartz sand, forming a strong and dense colored ceramic layer.
As functional decorative materials, glass-based luminous stones are crafted by fusing high-quality rare earth long-lasting luminous materials with glass substrates using special processes (such as high-temperature sintering or melting). They preserve glass’s crystal-clear appearance and hard texture, while being granted the distinctive property of self-luminating after dark—showcasing a clear, cool, and highly contemporary optical effect. They are extensively utilized in garden road paving, wall guidance signs, safety warning lines, water feature design, kitchen countertops, bathroom walls, and lobby feature walls.
With their high strength and chemical stability, solid white glass microspheres excel as precision abrasives, polymer fillers, and reflective agents across aerospace, automotive, and electronics industries.
