Nanometer Silica

Product Overview
Nanometer silica is an amorphous white powder with various microstructures, such as spherical, flocculent, or network-like quasi-particles. Its surface is rich in unsaturated residual bonds and multiple hydroxyl groups, which contribute to its excellent performance in a wide range of applications. The main preparation methods for nanometer silica include precipitation, sol-gel, and vapor-phase methods. It is commonly used in electronics, rubber, coatings, and biomedical fields.

Key Features

• High Surface Area:Due to its ultra-small particle size, nanometer silica offers an extremely high surface area, providing more active sites.
• Reflective Ability:It effectively reflects ultraviolet, visible, and infrared light, making it widely used in UV-protection applications.
• Biocompatibility:Nanometer silica has good biocompatibility, making it suitable for use in biomedical fields.

Applications

• Electronic Packaging Materials:Nanometer silica is widely used in the electronics industry, offering high dielectric properties, heat resistance, and high filler content.
• Rubber Modification:It enhances the tensile strength, tear resistance, and wear resistance of rubber, significantly improving its overall performance.
• Coatings and Adhesives:It improves the rheological properties and thixotropic behavior of coatings and adhesives, enhancing their anti-settlement and thickening effects.
• Optoelectronics:Used in optical sensors, solar cells, and display technologies, nanometer silica enhances the photoelectric conversion efficiency of dye-sensitized solar cells.
