Floating beads from Jinlin Corundum are hollow microspheres made of aluminosilicate ceramic, designed for thermal insulation in high-temperature industrial environments. These beads have a bulk density between 0.25 and 0.45 g/cm³ and a particle size range of 10 to 150 micrometres, as specified in the product data. They are supplied in bulk bags or 25kg drums for industrial handling and are engineered to withstand continuous exposure up to 1300°C without sintering or structural collapse.
The material composition follows standard aluminosilicate ceramic formulations used in refractory applications, with typical silica and alumina content ranging from 55% to 70% and 20% to 30% respectively. These values align with industry norms for lightweight insulating ceramics, though exact batch ratios are not disclosed by the supplier. The hollow structure provides low thermal conductivity, typically 0.06 to 0.09 W/m·K, making them suitable as fillers in insulating mortars, coatings, and composite panels.
These beads are primarily purchased by manufacturers of refractory bricks, fireproof coatings, and high-temperature insulation systems in steel, foundry, and glass industries. Buyers often integrate them into pipe insulation shells, riser sleeves, and fire-retardant paints to reduce heat loss and improve process efficiency. Trade is conducted in bulk quantities, with standard packaging in 25kg drums or 1000kg bulk bags. Lead time and minimum order quantities are not listed and must be confirmed directly with the supplier.

Before ordering, verify the exact particle size distribution, moisture content, and thermal conductivity with test reports from the supplier. Request a sample batch and perform a simple float-sink test to confirm hollow structure. Do not rely on marketing claims; insist on documented specifications matching your application’s thermal and mechanical requirements.
Confirm the Incoterms, lead time, and packaging options directly with Jinlin Corundum. Bulk shipments typically use FOB Ningxia port or CIF destination, with lead times ranging from 15 to 30 days after order confirmation. Payment terms are usually 30% advance and 70% against BL copy. Ask for container loading diagrams and export documentation standards.
For quality assurance, require a Certificate of Analysis (CoA) per batch showing particle size, density, moisture, and sphericity. Conduct incoming inspection using sieve analysis and a moisture meter. Retain a sample for future reference. Ensure the supplier provides SDS and export compliance documents, especially if importing into regions with strict chemical regulations.
