Nano Silica Spherical Powder Key Advantages

Regular Spherical Morphology: Perfect spherical structure with a smooth surface, effectively reducing stress concentration and improving the optical properties and rheology of composite materials.
Nanometer Size: Customizable particle size range (typically 20-500 nm) with excellent monodispersity, ensuring consistent and reliable product performance.
High Purity & High Specific Surface Area: Silica content exceeds 99.9% with minimal impurities. The large specific surface area provides abundant active sites for reactions.
Superior Stability: Excellent thermal resistance, corrosion resistance, and electrical insulation. It can withstand high-temperature environments and remains chemically stable.
Functionalizable Surface: The surface is rich in silanol groups, allowing for easy chemical modification (e.g., silanization) to enhance its dispersibility and compatibility in polymers or solvents.

Nano Silica Spherical Powder Applications

Electronic Packaging & ICs: Serves as a high-performance filler in epoxy molding compounds, effectively reducing internal stress and coefficient of thermal expansion, thereby improving device reliability.
High-End Coatings & Inks: Used as an additive to enhance coating properties like abrasion resistance, scratch resistance, anti-fouling, and UV stability.
Drug Delivery & Bio-imaging: An ideal carrier for pharmaceuticals or matrix for biomarkers, offering excellent biocompatibility and drug-loading capacity.
Precision Polishing (CMP): Applied in the ultra-precision polishing of semiconductor wafers and optical glass to achieve damage-free, high-gloss surfaces.
Advanced Composite Materials: Acts as a reinforcing filler to significantly improve the mechanical strength, heat resistance, and dimensional stability of matrix materials like rubber, plastics, and resins.

Nano Silica Spherical Powder Packing And Shipping

The Nano Silica Spherical Powder is securely packed in wooden crates or cartons, reinforced with cushioning materials to prevent movement during transit. This packaging approach ensures that the products remain intact and protected throughout the shipping process.
