Fumed silica—also known as pyrogenic silica—is a nanoscale inorganic, non-metallic material prepared via chemical vapor deposition (CVD). Its primary particle size typically ranges from 7 to 40 nanometers, and its specific surface area can reach 100 to 400 square meters per gram. It possesses unique physicochemical properties, including high purity, excellent dispersibility, a large specific surface area, and the presence of abundant silanol groups on its surface. Renowned as the “MSG of Industry” and the “Origin of Materials Science” due to its exceptional reinforcing, thickening, thixotropic, matting, and anti-settling capabilities, fumed silica plays an indispensable role across a wide array of industrial sectors.

Function
Fumed silica is widely utilized across various fields, including rubber, plastics, coatings, adhesives, cosmetics, food, pharmaceuticals, and electronics.
In the rubber industry, it serves as the most critical reinforcing filler for silicone rubber, significantly enhancing both tensile and tear strength.
In the electronics sector, it acts as a key abrasive material in Chemical Mechanical Polishing (CMP) slurries, employed for the precision planarization of semiconductor wafers.
In the food industry, it functions as an anti-caking agent, preventing products such as powdered milk and table salt from clumping.
In cosmetics, it serves as both a thixotropic agent and a sunscreen additive, imparting unique rheological properties and a distinctive skin feel to the final products.
