SiSiB has a wide range of hydrophilic pyrogenic silica for sale with different surface area. SiSiB high purity sio2 hydrophilic fumed silica is manufactured by hydrolysing volatile chlorosilanes in an oxyhydrogen flame.

In chemical terms, the loose white silicone powder consists of highly pure amorphous silicon dioxide. Hydrophilic silica is wetted by water and can be dispersed in water. They have good temperature resistance, chemical resistance and thixotropic properties.

Fumed silicas by SiSiB, a reliable silicone manufacturing company, are widely used in adhesives & sealants, silicone elastomers, coatings & inks, composites, personal care cosmetics and fire extinguisher. SiSiB fumed silicas are used to for rheology control (thickening, anti-sag, anti-setting, thixotropy), reinforcing (improve strength). SiSiB fumed silicas provide good scratch and abrasion resistance, free-flow and anti-caking, corrosion resistance, and enhanced adsorbency.

Sio2 hydrophobic fumed silica powders supplied by SiSiB are useful for thickening non-polar solvents such as xylene, styrene and mineral spirits. When fumed silica is dispersed in a non-polar liquid, the silanol groups on the surface of different particles can interact through hydrogen bonding to form a bridge. A three-dimensional structure is formed with a thickening effect.
