Silica, identified by the CAS number 10279-57-9, is a compound whose scientific properties make it exceptionally valuable across a multitude of industrial applications. This white powder, composed primarily of silicon dioxide (SiO2), is characterized by its high purity, fine particle size, and unique surface chemistry. NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of this essential material, ensuring manufacturers have access to consistent quality for their formulation needs.

The core scientific advantage of silica lies in its high SiO2 content, which typically exceeds 93%. This purity ensures predictable performance and minimal interference with other chemical reactions within a formulation. The particle size, often in the range of 40 micrometers for certain grades, and specific surface area, measured by BET, are critical parameters that dictate its functional behavior. For instance, a BET surface area of 140-170 m²/g indicates a significant capacity for interaction and adsorption.

In applications like paints and coatings, silica's physical structure contributes to rheological control and pigment suspension. Its ability to absorb oil, measured as DBP (dibutyl phthalate) absorption, influences the viscosity and flow characteristics of liquid systems. Grades with a DBP absorption of 2.30-2.60 are commonly specified for tasks like thickening and preventing sagging.

For the rubber industry, silica acts as a reinforcing filler. The chemical interaction between silica particles and rubber polymers, often facilitated by silane coupling agents, leads to enhanced mechanical properties such as tensile strength and tear resistance. This reinforcement is vital for components that endure significant stress, such as tire treads.

NINGBO INNO PHARMCHEM CO.,LTD. prides itself on being a reliable supplier of silica in China, offering various grades tailored to specific industrial requirements. Whether it’s for use as a plastic tackifier, a grease thickener, or a general industrial filler, understanding the scientific underpinnings of silica's performance is key.
