Fumed silica, due to its unique characteristics such as small particle size and large specific surface area, has shown wide application value in many fields.

In silicone rubber, fumed silica serves as a reinforcing agent, which can significantly improve the strength, wear resistance and anti-aging properties of the rubber. In the field of coatings and inks, it acts as a thixotropic agent to effectively prevent pigments and fillers from settling and stratifying, and improves the scratch resistance of the paint film. In addition, in adhesives and sealants, fumed silica not only plays a role in rheology control, but also enhances the reinforcing effect of the product.

Not only that, fumed silica also has significant applications in composite materials, plastics, optical materials and other fields. In composite materials, it acts as a thickener and thixotropic agent, optimizing material properties. In plastics, it makes the plastic denser, increasing clarity and strength. Among optical materials, fumed silica is used to make multi-layer interference films to improve the light transmittance and energy-saving effect of lamps.

In conclusion, the versatility of fumed silica makes it an indispensable and important material in many industrial fields.
