PRODUCT INFORMATION

Wacker Fumed Silica is a medium surface fumed silica that imparts significant increase in viscosity in liquid systems, free flow of powders, and reinforcement of silicone and organic rubbers.

 

Wacker Fumed Silica is widely used to provide thickening, thixotrophic (shear-thinning), and anti-settling behavior in liquid systems. Wacker Fumed Silica is most efficient in non-polar to medium polarity systems. For more polar systems, treated fumed silicas are more effective. Wacker Fumed Silica offers the best balance of thickening efficiency and dispersibility.

 

Free-flow of Powder Systems:

When blended into sticky and poorly flowing powder systems, Wacker Fumed Silica reduces angle of repose and improves powder flow. During storage of powder systems, Wacker Fumed Silica reduces caking and blocking.

 

Reinforcement of Silicone and Organic Rubber:

Wacker Fumed Silica can be used for reinforcement of silicone rubber and can be used to reinforce organic rubbers. It imparts good increase in hardness, tensile, and elongation.
