Precipitated Silica ALOS-PS-001
Inquiry
Precipitated silica ALOS-PS-001 is a high-purity, synthetic amorphous silicon dioxide produced by controlled precipitation from silicate salt solutions. The material is odorless, chemically inert, and non-crystalline, with a very high specific surface area and open porosity that deliver excellent absorbency and versatile performance in formulations.

Applications
- Rubber industry: Precipitated silica ALOS-PS-001 serves as a high-performance reinforcing filler in the rubber industry. Its high surface area and optimized pore structure create strong polymer–filler interactions, enhancing tensile strength, tear resistance, and abrasion durability in tires, belts, and hoses.
- Food industry: In the food sector, this product functions as an efficient anti-caking and flow-improving agent. By adsorbing trace moisture, it prevents clumping in powdered seasonings, milk powders, and instant drink mixes, ensuring consistent free-flow behavior during handling and packaging. Additionally, its porous matrix can act as a carrier for flavors, vitamins, and natural extracts, stabilizing sensitive ingredients and enabling controlled release in the final product.
- Pharmaceuticals: Within pharmaceutical formulations, this product is valued for its multifunctional excipient properties. As a glidant and flow enhancer, it promotes uniform powder metering and smooth tablet compression or capsule filling.
- Personal care and cosmetics: In personal care and cosmetics, ALOS-PS-001 improves texture, stability, and sensory feel across a wide range of products. It acts as a rheology modifier in creams and lotions, delivering a smooth, non-greasy finish, and as an oil-absorbing agent in powders and mattifying masks.
