Hydrophilic silica is a high-purity amorphous silicon dioxide (SiO2) powder with a strong affinity for water, making it ideal for applications requiring dispersion in aqueous systems. The surface of the particles is functionalized with hydroxyl groups, enabling hydrogen bonding with water molecules. This property is critical for its use as a thickening agent, reinforcing filler, or anti-settling additive in industrial formulations.
The material is available in various particle sizes, typically ranging from 5 nm to 50 microns, with BET surface areas between 50-400 m²/g depending on the grade. High-purity hydrophilic silica, with SiO2 content exceeding 99.5%, is standard for electronic and pharmaceutical applications. In rubber compounds, it improves tensile strength and abrasion resistance, while in coatings, it enhances rheological properties and stability.
Primary buyers include manufacturers of elastomers, sealants, adhesives, and coatings, as well as pharmaceutical and food producers requiring functional excipients. Bulk packaging usually consists of 25 kg kraft paper bags with moisture barriers or jumbo bags for large-scale orders. Buyers should confirm particle size distribution, surface area, and pH levels to match their specific formulation needs.

Before ordering, verify the supplier’s certificates of analysis for key parameters such as SiO2 purity, particle size distribution, BET surface area, and moisture content. Request samples to test dispersion stability and compatibility with your specific formulations. For pharmaceutical or food applications, ensure the product meets relevant regulatory standards and has the necessary certifications.
Discuss logistics details, including lead times, which can vary from 20 to 60 days depending on production schedules and order volume. Confirm Incoterms, with FOB or CIF Tianjin/Shanghai being common for exports from China. Payment terms often include a 30% deposit with the balance due before shipment, but these should be tailored to your order size and supplier agreement.
Inspect incoming shipments for consistent particle size, absence of clumping, and moisture levels within specification. For rubber applications, test the silica’s reinforcement properties in your compound to ensure it meets performance targets. Request documentation such as MSDS, COA, and compliance certificates for ISO 9001 or REACH to confirm quality and regulatory adherence.
