Feature
Hydrophilic Fumed Silica has several applications due to its unique properties. It is commonly used as a thickening
and suspending agent in various industries, including paints, coatings, adhesives, cosmetics, and pharmaceuticals.
It can also be used as a reinforcing filler in rubber and plastics, as well as a flow aid in powders and granular materials.
There are some common applications.
1. Rubber and Plastics: Hydrophilic Fumed Silica is used as a reinforcing agent and viscosity modifier in rubber and plastic
compounds. It improves the mechanical properties, such as tensile strength and tear resistance, and enhances the
processability of these materials.
2. Inks and Toners: Hydrophilic fumed silica is used in inks and toners as a rheology modifier and dispersing agent. It helps
in controlling the flow properties, preventing sedimentation of pigments, and improving the print quality and stability of these
products.
3. Energy Storage: Hydrophilic fumed silica is used in lithium-ion batteries as a conductive additive and binder. It improves
the electrical conductivity and mechanical strength of the electrode materials, enhancing the performance and cycle life of
the batteries.
These are just a few examples of the applications of hydrophilic fumed silica. Its unique properties make it a valuable additive
in various industries, where it helps in improving the performance, stability, and processability of different products.
