99.9% Nano silica
Nano-silica has the characteristics of small particle size, large number of micropores, large specific surface area, high surface hydroxyl content, strong reflection ability to ultraviolet light, visible light and infrared light. Especially with the improvement of the surface treatment process of the product, the soft agglomeration degree of the nano particles is obviously reduced, and the compatibility with the organic polymer material is good, which greatly broadens the application field of the product.
