Understanding the precise technical specifications of Silica Gel (CAS 112926-00-8) is fundamental for leveraging its full potential across diverse industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes these critical parameters, as they directly dictate the material's performance as a matting agent, thickener, anti-adhesive agent, and stabilizer. This article breaks down the key specifications and their implications.

At the forefront is the Assay, which at a minimum of 99%, guarantees a high concentration of active silicon dioxide (SiO2 content up to 99.7%). This high purity is vital for predictable chemical interactions and performance in sensitive applications like food and pharmaceuticals. The Appearance as a white powder is standard, but its high Whiteness of 95% is significant for applications where color neutrality is important, such as clear coatings or light-colored plastics.

The BET surface area, typically around 220 m²/g, is a measure of the total surface area available for adsorption and interaction. A higher BET value generally correlates with greater adsorptive capacity and thickening efficiency. Coupled with this is the DBP absorption, usually around 290 ml/100g, which indicates the pore volume and structure, influencing its performance as a thickener and reinforcing agent. These properties contribute to its efficacy in controlling viscosity and providing desired rheological behavior in formulations.

Particle size is another critical parameter, often specified by D50 (median particle size) of approximately 3µm. This fine particle size is crucial for achieving smooth surfaces in coatings (matting), effective separation in plastic films (anti-adhesion), and uniform dispersion in powdered products. The Drying loss (at 105℃ ≤ 3.0%) and Ignition loss (at 1000℃ ≤ 4.0%) indicate the residual moisture and inorganic content, respectively, further confirming the material's purity and thermal stability. The pH Value of 7.0 ensures it is neutral and unlikely to cause adverse reactions in most formulations.
