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
This DMF-free white silica gel is a fine-pored Type-A desiccant offered as beads for static drying. The material is described as transparent or semitransparent with a glass-like appearance. Listed size grades are 1–3 mm, 2–4 mm, 3–5 mm, 4–6 mm, and 5–7 mm.
Supported technical data include an average pore diameter of 2.0–3.0 nm, specific surface area of 650–800 m²/g, pore volume of 0.35–0.45 ml/g, specific heat of 0.92 kJ/kg-°C, and thermal conductivity of 0.63 kJ/m-hr-°C.
The specification table reports silicon dioxide content of at least 98.5%, heat loss of no more than 1.0%, pH 4, specific resistance of at least 5,630 Ω-cm, and at least 90% pass for spherical particles.
Typical moisture-absorption capacity is listed as at least 11.2% at 20% relative humidity, 29.2% at 50% relative humidity, and 37.6% at 90% relative humidity. A 3–5 mm grade is shown with a bulk density of 784 g/L.
Stated uses include desiccation and moisture absorption, as well as service as a catalyst carrier, adsorbent, separating agent, and pressure-swing absorber.
Buyers should evaluate the selected grade against their operating humidity, particle-size tolerance, pressure-drop requirements, regeneration process, and equipment design. Before purchasing, confirm which reported values are guaranteed specifications versus typical data for the requested lot.
Also verify the required particle-size grade, bead or lumpy form, test method for DMF-free status, moisture level at shipment, packaging configuration, batch documentation, storage requirements, and suitability for the intended process.
The listed transport package is a plastic bag at 25 kg per bag, but final packing and order conditions should be confirmed for the specific procurement.
