Import Fine-Pore Water-Proof Silica Gel — Buy in Bulk from Supplier in China

Fine-pore water-proof silica gel is a desiccant designed with a fine-pore structure and a waterproof coating to absorb moisture while resisting liquid water. The gel’s fine pores increase its surface area, allowing rapid adsorption of water vapour from the surrounding environment. It is supplied in bulk form, suitable for large‑scale industrial use. The product description supplied by the vendor lists waterproof performance and fine‑pore architecture as its key attributes.

In the silica‑gel industry, typical pore diameters range from 60 to 200 Å and provide a BET surface area around 600 m² g⁻¹, which is considered standard for high‑capacity desiccants. Moisture adsorption capacity is typically about 40 % of the gel’s weight at 25 °C and 80 % relative humidity. Particle size is commonly 0.5‑2 mm, giving good flowability during handling. The waterproof coating is usually a silane‑based layer that prevents liquid water ingress while preserving vapour adsorption.

The gel is used by manufacturers in pharmaceuticals, electronics and food‑packaging to protect moisture‑sensitive components and extend product shelf life. Distributors and bulk purchasers can order the material in standard 25 kg polypropylene bags or larger bulk containers, depending on logistics needs. Shipping terms offered include FOB and CIF, and payment methods such as L/C and T/T are accepted. Buyers should confirm the exact minimum order quantity and any required certifications directly with the supplier before placing an order.
