At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on delivering materials that meet the highest technical standards. Our bio-based silica NS175 MS is a prime example, offering a unique combination of performance-driven properties derived from a sustainable source. Understanding these technical specifications is key to appreciating its value in various industrial applications.

The core of our NS175 MS lies in its composition as a high-performance white carbon black. It is characterized by its white color and amorphous micro-pearl structure, ensuring it integrates seamlessly into formulations without imparting unwanted coloration. Key physical properties include a specific surface area (BET) of 175 ± 15 m²/g and a CTAB surface area of 165 ± 15 m²/g. These parameters are crucial for its efficacy as a reinforcing filler, indicating a high surface area available for interaction with polymer matrices.

The dispersibility and chemical stability of our bio-based silica are further enhanced by a DBP absorption value of 2.0-3.5 cm³/g. This metric provides insight into how well the silica will disperse within a rubber compound or coating matrix, directly impacting the final product's mechanical properties and uniformity. The material also boasts a high silica content (dry basis) of ≥95%, with controlled drying loss (4.0-8.0%) and ignition loss (≤7.0%), ensuring purity and consistency.

Its pH range of 5.0-8.0 (10% aq) indicates a neutral to slightly acidic nature, which is beneficial for compatibility with various polymer systems and processing conditions. Furthermore, stringent controls on trace metal impurities like Copper (Cu ≤10 mg/kg), Manganese (Mn ≤40 mg/kg), and Iron (Fe ≤500 mg/kg) ensure its suitability for sensitive applications, including those in the food or pharmaceutical industries if regulations permit.

As a rubber reinforcing agent, these properties translate into tangible benefits such as improved tensile strength, tear resistance, and reduced hysteresis in rubber compounds, particularly for tires and shoe soles. In coatings, it contributes to enhanced film hardness, abrasion resistance, and matting effects. The non-toxic and non-combustible nature of our amorphous silica further adds to its appeal as a safe and versatile inorganic compound. By focusing on these detailed technical aspects, NINGBO INNO PHARMCHEM CO.,LTD. ensures that our bio-based silica NS175 MS stands out as a leading choice for manufacturers seeking premium, sustainable material solutions.
