Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Silica Gel. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
Product overview This water-resistant, fine-pore silica-alumina gel is supplied as microcrystalline beads in 2–4 mm or 3–5 mm sizes. It is intended primarily for industrial moisture-adsorption duties where liquid water may be present in the system.
The material may be installed as a protective layer for fine-pore silica gel or fine-pore silica-alumina gel, or used independently under conditions involving a high liquid-water content. Supported applications The stated applications include drying air, compressed air, and industrial gases.
The gel is also described for ethyne adsorption during the preparation of liquid oxygen or liquid nitrogen. Additional stated uses include operation as a liquid adsorbent or catalyst carrier in oil-chemical, electrical, and brewery processes. Reported properties The specified Al₂O₃ content is 10.0–17.0%.
Specific surface area is at least 450 m²/g, bulk density is at least 670 g/L, and crush strength is at least 80 N per bead. Pore volume is 0.35–0.50 ml/g, while loss on heating is no more than 3.0%.
Reported adsorption capacity at 25°C is at least 3.0% at 20% relative humidity, 6.0% at 40% relative humidity, and 30.0% at 80% relative humidity. Storage and handling The product should not be exposed to open air.
It should be stored under dry conditions in airtight packaging to limit unintended moisture uptake before use. Procurement questions to confirm Before ordering, buyers should confirm the required bead size, order quantity, packaging format, and whether sample-based customization is suitable for the project.
The supplier should also be asked to confirm the test methods and acceptance tolerances behind each reported property, provide lot-specific quality documentation, and verify suitability for the buyer’s actual gas composition, pressure, temperature, flow rate, liquid-water load, regeneration method, and equipment design.
For oxygen or nitrogen production duties, buyers should complete their own process-safety and compatibility review before approval.
