Characteristics
Organic hydrophilic fumed silica powder is a type of silica powder that is specially treated to have a hydrophilic (water-attracting)
surface. It is commonly used as an additive in plastics to improve their properties.
Fumed silica is a fine, white powder that is made by burning silicon tetrachloride in a flame of hydrogen and oxygen. This
process creates tiny particles of amorphous silica, which have a high surface area and unique properties.
When fumed silica is treated with organic compounds, it becomes hydrophilic, meaning it has an affinity for water. This makes
it useful in plastic applications where moisture resistance is important.
In plastics, organic hydrophilic fumed silica powder can be used as a reinforcing filler to improve mechanical properties such
as tensile strength, tear resistance, and dimensional stability. It can also enhance the flow and processability of the plastic
