Discover the marvel of our Premium White Precipitated Silica, expertly crafted through an innovative wet chemical precipitation process. This results in a synthetic amorphous silica (SiO2) with remarkable versatility and exceptional properties. Unlike its vapor-phase counterpart, our silica is produced through a sustainable, low-energy water treatment that ingeniously combines sodium silicate and mineral acids. This process yields a highly porous, vast-surface-area material with customizable particle sizes and morphologies. Its extraordinary blend of reinforcing, thickening, and matting traits makes it an essential component across a range of industries, including rubber, plastics, and specialty chemicals. In the rubber industry, it revolutionizes tire production by replacing carbon black and reducing rolling resistance, and it enhances shoe soles. Its benefits extend to personal care as a toothpaste abrasive and paint matting agent. In the food and feed sectors, it acts as a superior anti-caking agent, improving flow in powdered foods and as a carrier. It's also pivotal in agriculture as a slow-release carrier for pesticides.

Rubber and Plastics
Our silica serves as a high-performance reinforcing filler in rubber and plastic materials, significantly enhancing mechanical attributes including tear strength, abrasion resistance, and dimensional stability. Its inclusion elevates the processability and overall performance of rubber and plastic compounds, setting a new standard for hydrophilic fumed silica applications.
Food and Beverages
As a masterful additive, our silica functions as an anti-caking agent, viscosity modifier, and stabilizer in food and beverage applications. This hydrophilic fumed silica elevates the flowability, texture, and stability of powdered mixes, sauces, and beverages, ensuring a consistently superior product experience.
