Key Features and Benefits
High Surface Area: With a specific surface area of 200 m²/g, our fumed silica provides excellent thickening and reinforcing properties.
Thixotropy and Rheology Control: It offers superior rheology and thixotropy control, improving the consistency and flow characteristics of silicone rubber compounds.
Reinforcement: Adding Fumed Silica 200 to silicone rubber enhances its mechanical properties, including tensile strength, tear resistance, and modulus.
Anti-Settling and Anti-Sagging: It acts as an effective anti-settling and anti-sagging agent, preventing the separation of components in liquid systems.
Free Flow and Anti-Caking: Fumed Silica 200 improves the flow characteristics of powders and prevents caking, ensuring easy handling and storage.
