What Is High alumina silica cenophere for construction?

▸ This product is selected for construction materials that require lower density, improved insulation, and mineral durability.

▸ The hollow ceramic microspheres reduce material weight and help improve thermal performance in cementitious systems.

▸ Mesh size should be matched with mortar, slurry, panel, or dry-mix processing requirements.

Key Performance Characteristics

▸ Weight Reduction: Low-density hollow spheres reduce the weight of mortar, panels, and cement products.

▸ Thermal Insulation: The hollow core helps lower heat transfer in building material systems.

▸ Cement Compatibility: Aluminosilicate chemistry is suitable for many cement and gypsum formulations.

▸ Workability Support: Spherical particles can improve mixing and application feel.

▸ Durable Mineral Filler: Inorganic ceramic particles provide stable long-term filling performance.

FAQ – Coating Grade Cenospheres

❓ What is the typical particle size range for CENOLITE 910?

▸ D50 = 45-60 μm, D98 = 105-140 μm, optimized for thin-film and industrial coatings.

❓ Why is iron content important for coating applications?

▸ Low iron (≤6%) ensures lighter color and better opacity, especially for white or light-colored paints and primers.

❓ Do you test dispersion performance?

▸ Yes, every batch is tested with high-speed mixing and Hegman gauge to ensure no agglomeration and uniform dispersion in paint systems.

❓ Can you provide a COA with every shipment?

▸ Yes, each shipment includes a digital Certificate of Analysis with batch-specific test results.

❓ Can you customize particle size for a specific coating resin?

▸ Yes, we offer custom cuts (e.g., D50=30-40μm for high-gloss finishes) upon request.
