Fumed Silica, such as Erosil-NV/200, is a type of amorphous, nano-sized silica produced by the vapor-phase hydrolysis of silicon compounds is a type of high-purity amorphous silica that is widely used in various industries due to its unique properties. In masterbatch applications, fumed silica can serve several purposes and provide several benefits.
Here are some common uses and applications of fumed silica in masterbatch formulations:
Rheology control: Fumed silica is often used as a thickening and thixotropic agent in masterbatch formulations. It helps control the viscosity and flow characteristics of the molten polymer, making it easier to process and handle during manufacturing. By adjusting the concentration of fumed silica, manufacturers can achieve the desired rheological properties in their masterbatch.
Reinforcement: Fumed silica can enhance the mechanical properties of the final product by acting as a reinforcing filler. It improves the tensile strength, tear resistance, and dimensional stability of the polymer matrix when incorporated into the masterbatch. This is particularly beneficial when the masterbatch is intended for applications that require high strength and durability.
Anti-blocking agent: Fumed silica can also be used as an anti-blocking agent in masterbatch formulations. It helps prevent the sticking or blocking of polymer surfaces, especially in applications where the masterbatch is used as a coating or film. By incorporating fumed silica, the masterbatch can improve the slip and release properties of the final product, making it easier to handle and process.
Anti-sagging agent: In applications where the masterbatch is used in vertical or overhead coatings, fumed silica can act as an anti-sagging agent. It improves the thixotropic behavior of the formulation, reducing the tendency of the coating to sag or drip when applied to vertical surfaces.
UV stability: Fumed silica can provide UV stability to the masterbatch formulation. It acts as a UV absorber, helping to protect the polymer matrix from the damaging effects of ultraviolet radiation. This is particularly important in applications where the masterbatch is exposed to sunlight or other sources of UV light.
Surface modification: Fumed silica can be surface-modified to introduce functionalities or improve compatibility with the polymer matrix in masterbatch formulations. Surface treatments such as silane or organosilane coatings can enhance the dispersion of the fumed silica within the polymer, leading to improved performance and properties in the final product.
It’s worth noting that the specific application and dosage of fumed silica in masterbatch formulations may vary depending on the desired properties, the polymer matrix used, and the manufacturing process. Therefore, it is important to consult with the manufacturer or supplier of the fumed silica for detailed guidelines and recommendations tailored to your specific application.
