The effect of Silica on the conductive properties of silicone is significant, and it mainly affects the conductive properties of silicone in the following aspects:

1. Formation of Conductive Network
As a conductive filler, Silica can be evenly dispersed in silicone to form a connected structure. This connected structure helps the transmission of electrons in silicone, thereby improving the conductive properties of silicone. Therefore, adding an appropriate amount of Silica to silicone can make it have a certain conductivity, which is widely used in electronic products, electrical equipment and other fields.

2. Improvement and suppression of conductive properties
Improvement of conductive properties: When the content of Silica increases within a certain range, the conductive properties of silicone will be enhanced accordingly. This is because more Silica particles can form more conductive channels, which is conducive to the transmission of electrons.
Suppression of conductive properties: However, when the content of Silica is too high, it may cause the mechanical strength of silicone to decrease, and too many Silica particles may hinder the transmission of electrons, which in turn reduces the conductive properties of silicone. In addition, if the interaction between Silica and silicone is not good, it may also affect the improvement of conductive properties.

3. Influencing factors and conditions
Types and properties of silica: Different types of silica have different conductivity and dispersion properties. Therefore, when selecting silica, it is necessary to consider the effects of its type, specific surface area, particle size and other factors on the conductivity of silicone.
Silica gel substrate and formula: The substrate and formula of silica will also affect the effect of silica on the improvement of conductivity. For example, some silica gel substrates may have better compatibility with silica, which is more conducive to the formation of a conductive network.
Processing conditions and technology: Factors such as temperature, pressure, and time during processing will also affect the dispersion of silica in silica and the formation of a conductive network. Therefore, it is necessary to optimize the processing conditions and technology to obtain the best conductive properties.

4. Application examples and effects
In electronic products, such as conductive silicone buttons and conductive rubber strips, silica is often added to improve the conductivity of silicone. Through reasonable formula design and processing condition control, silicone products with excellent conductive and mechanical properties can be obtained. These products play a role in connection, conduction and sealing in electronic products, improving the reliability and stability of the products.

In summary, the influence of white carbon black on the conductivity of silicone is complex and multifaceted. By rationally controlling the content, type and properties of white carbon black as well as processing conditions and processes, the conductivity of silicone can be optimized and improved.
