Specification

Colloidal powder amorphous Fumed Silica is a type of silica that is used in the production of silicon rubber. It is a fine, white

powder that is made up of small particles of silicon dioxide.

Fumed silica is produced by burning silicon tetrachloride in a flame of hydrogen and oxygen, which creates silicon dioxide

particles. These particles are then collected and processed into a powder form.

In the production of silicon rubber, colloidal powder amorphous fumed silica is added to the rubber compound as a reinforcing

filler. It helps to improve the mechanical properties of the rubber, such as tensile strength, tear resistance, and abrasion

resistance.

The addition of fumed silica also enhances the processability of the rubber compound, making it easier to mix and mold. It

improves the flow properties of the rubber, allowing for better dispersion of other ingredients and reducing the risk of defects

in the final product.

Furthermore, colloidal powder amorphous fumed silica can also improve the thermal stability and electrical insulation properties

of silicon rubber. It helps to reduce the risk of heat degradation and enhances the resistance to electrical current flow.

Overall, colloidal powder amorphous fumed silica is an important ingredient in the production of silicon rubber, providing

enhanced mechanical properties, processability, thermal stability, and electrical insulation..

Feature

1. Used as anti-settling, thickening, anti-sagging agent.

2. Improvement of free flow and anti-caking characteristics of powders.

3. Rheology and thixotropy control of liquid systems, binders, polymers,etc.
