Specialty Silica

Hydrophobic precipitated silica, also known as high-performance hydrophobic silica, is a kind of silica material with high purity and oligosilicic acid as its raw material. It has a very small particle size, low surface area and high surface activity, and it is not affected by acid and alkali. Hydrophobic precipitated silica has high surface activity, and its hydrophobicity index ranges from 0.28 to 0.75, indicating that the surface of the material can effectively resist water. It has excellent performance in oil absorption, uniform particle size distribution and high specific surface area. It is light yellow in appearance and has a moisture absorption rate of less than 1%. Hydrophobic precipitated silica is widely used in rubber products such as tires, rubber shoes and belts as anti-skid agent. It is also used in daily medicines and beauty products, paint, coating, and printing ink as filtering agent and reinforcing agent. In addition, it can also be used in building materials, such as ceramics, tiles, putty powder, waterproof material and fire-proof material, which can promote the solidification of these materials. In the agricultural sector, it can also be used as a nutrient The main differences between the speciality silica and gerneral product lines are in specific surface, behaviour to water and particle size.
