Feature
High purity white Hydrophilic Fumed Silica powder is a type of Silica Powder that has been treated to be hydrophilic, meaning
it has a strong affinity for water. This makes it ideal for use in applications where moisture absorption or dispersion is
important.
Fumed Silica Powder is a fine, white powder that is made by burning silicon tetrachloride in a flame of hydrogen and oxygen.
This process creates very small particles of silica that have a high surface area and are highly reactive.
The high purity of this Fumed Silica powder means that it is free from impurities and contaminants, making it suitable for use in
sensitive applications such as pharmaceuticals, cosmetics, and food products.
Some common uses for high purity white hydrophilic fumed silica powder include as a thickening agent in lotions and creams,
as a flow aid in powdered products, and as a reinforcing filler in rubber and plastic materials. It can also be used as a desiccant
or absorbent in various industrial processes.
Overall, high purity white hydrophilic fumed silica powder is a versatile and valuable material that can enhance the performance
of a wide range of products and processes.
