Nano Silica Powder

Nano silica is characterized by small particle size, numerous micropores, large specific surface area, and high surface hydroxyl content. It is resistant to ultraviolet rays and It has the characteristics of strong light and infrared reflection ability, etc. Especially with the improvement of the surface treatment process of the product, the soft clusters of nanoparticles. the degree of polymerization is significantly reduced, and it has good compatibility with organic polymer materials, which greatly expands the application fields of the product.
