Specification
Colloidal powder Amorphous Fumed Silica is a type of silica that is commonly used as a reinforcing filler in silicon rubber.
It is a fine, white powder with a high surface area and a unique structure, which gives it excellent reinforcing properties.
When added to silicon rubber, colloidal powder amorphous Fumed Silica helps to improve the mechanical properties of the
rubber, such as tensile strength, tear resistance, and abrasion resistance. It also enhances the dimensional stability and
heat resistance of the rubber.
The small particle size and large surface area of colloidal powder amorphous fumed silica allow it to form a network-like
structure within the rubber matrix, increasing its strength and stiffness. This results in improved performance and durability
of silicon rubber products.
In addition to its reinforcing properties, colloidal powder amorphous fumed silica also acts as a thickening and thixotropic
agent in silicon rubber. It helps to control the viscosity and flow properties of the rubber during processing, making it easier
to handle and mold.
Overall, colloidal powder amorphous fumed silica is a crucial ingredient in the formulation of silicon rubber products, providing
improved mechanical properties, dimensional stability, heat resistance, and processability.
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.
