Nano Silica Fumed Powder - High-Quality Suppliers and Factory in China for Ultra-Fine SiO₂材料

Nano silica, also referred to as fumed silica, is a high-performance inorganic chemical material produced in China by leading suppliers and factories. This ultra-fine nanomaterial, with particle sizes ranging from 1 to 100 nm, is renowned for its unique characteristics including UV resistance and the enhancement of aging resistance, strength, and chemical durability in various applications. Presented as an amorphous white powder, nano silica is non-toxic, odorless, and environmentally friendly. Its microstructure is characterized by spherical, flocculent, and network-like quasi-particles. With a molecular and structural formula of SiO₂, it is also insoluble in water, making it an ideal choice for numerous industrial uses
