Hydrophobic nano-silica (KH570 modification)

Product Name Hydrophobic nano-silica (KH570 modification) Product Overview Nanosilica has a basic structure of SiO₂ and exists as an amorphous white powder; its microstructure can take the form of spherical, flocculent, or network-like quasi-particle structures. Its surface contains unsaturated residual bonds and hydroxyl groups with different bonding configurations—properties that enable it to perform exceptionally well in a wide range of applications. This product is prepared using the vapor-phase synthesis method. Technical Parameter Diameter: 20-200 nm (TEM); Appearance: White powder; Purity: ≥99wt%(XRF) Product Features High specific surface area: Due to its small particle size, nano-silica possesses an exceptionally high specific surface area, which provides it with a greater number of active sites. Reflective properties: It effectively reflects ultraviolet, visible, and infrared radiation, making it highly suitable for numerous applications requiring UV protection. Biocompatibility: Nano-silica exhibits excellent biocompatibility and can be utilized in the biomedical field.. Application Fields Electronic packaging materials: Due to their high dielectric constant, high thermal resistance, and high filler content, these materials are widely used in the electronics and electrical appliances industry. Rubber modification: This enhances the tensile strength, tear resistance, and wear resistance of rubber products, significantly improving their overall performance. Coatings and adhesives: These applications are used to improve the rheology and thixotropy of coatings and adhesives, as well as to enhance their anti-settling and thickening properties. Optoelectronic field: These materials find extensive applications in optical sensors, solar cells, display technologies, and other areas—for example, in improving the photoelectric conversion efficiency of dye-sensitized solar cells.
