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 Type A white silica gel is supplied as milky-white, transparent, or translucent beads for drying and moisture-control duties.
The stated technical data specifies SiO2 content of at least 98%, a pore diameter of 20–30 Å, bulk density of at least 720 g/L for the spherical grade, and a qualified size ratio of at least 98%. Available spherical particle ranges include 0.5–1.5 mm, 1–3 mm, 2–4 mm, 3–5 mm, 2–5 mm, and 4–8 mm.
Moisture adsorption is specified after 48 hours at 25°C: at least 8% at 20% RH, at least 22% at 50% RH, and at least 32% at 90% RH. Loss on heating is listed as a maximum of 2.0% or 5.0%, so buyers should identify the required grade and test limit in the purchase specification.
The material is described for drying and moisture proofing and may also be used as an adsorbent, catalyst carrier, separator, or variable-pressure adsorbent. Stated industry contexts include gas and oil, food, pharmaceuticals, fine chemicals, scientific analysis, environmental monitoring, and petrochemicals.
Suitability for any regulated, food- , pharmaceutical, or process-critical use should be confirmed against application-specific documentation before purchase. Standard packing options are 25 kg bags, 25 kg drums, 150 kg drums, and 800 kg jumbo bags.
Customization from samples or designs, as well as OEM and ODM service, is stated as available. Each lot is stated to be tested before loading.
Before ordering, confirm the required bead size, adsorption test method and acceptance values, loss-on-heating grade, packaging, order quantity, inspection documents, and batch traceability.
Buyers should also request the current safety data sheet, certificate of analysis, and relevant certification records, and verify whether the selected grade meets their intended process and regulatory requirements.
