HJSIL® Fumed Silica - not only SiO2

Fumed silica, also known as pyrogenic silica, is a highly dispersed, fine particle form of silicon dioxide (SiO2). It is made by vaporizing silicon tetrachloride (SiCl4) in a high-temperature flame, which creates small, highly reactive particles that condense into a fine powder.

HJSIL® fumed silica is a brand of fumed silica that is manufactured and marketed by Minmetals East Industrial, a leading chemical company based in China. HJSIL fumed silica is characterized by its high purity, high surface area, and excellent dispersibility. It has a unique combination of properties that make it useful in a wide range of applications, including:

Features of HJSIL® fumed silica

- High surface area:

Fumed silica has a high surface area, which makes it an effective thickening agent and improves its ability to reinforce and strengthen other materials.

- Excellent dispersibility:

Fumed silica is highly dispersed in liquids and other materials, which improves its ability to be evenly distributed and incorporated into a wide range of products.

- Low bulk density:

Fumed silica has a low bulk density, which makes it useful as a filler material in composites and other materials.

- Good chemical stability:

Fumed silica is highly resistant to chemical attack, which makes it useful in applications where resistance to harsh chemicals is required.

- Thermal stability:

Fumed silica is highly stable at high temperatures, which makes it useful in high-temperature applications.

Fumed silica is used in a wide range of products, including adhesives, Rubbers And Plastics, Coatings And Paints, rubber, Silica Insulating Panels and VIPs, and composites. Its unique combination of properties makes it an important material in many industries, including electronics, aerospace, construction, and consumer goods.
