The Secrets of Silicon Dioxide
2025-03-27
Silicon dioxide, including silicon dioxide for the rubber industry, feed additives, and other applications, is mainly used in the following areas.
How does the addition of nano-silica affect the performance of rubber?
2025-03-27
When the amount of nano-silica added is low, the tensile strength of the rubber usually increases with the increase of the amount added. This is because nano-silica can act as a reinforcing agent, forming physical or chemical adsorption with rubber molecular chains. For example, in natural rubber, when the amount of nano-silica added increases from 0 to 5 phr (parts per hundred rubber), the tensile strength may gradually increase. The reason is that nano-silica particles interact with rubber molecular chains, and can effectively transfer and disperse stress during stretching, preventing the slippage of rubber molecular chains, thus improving tensile strength.
Silicon dioxide plays a significant role in many fields

Silicon dioxide, an inorganic new material, plays an irreplaceable role in many fields. In particular, nano-silicon dioxide, with its small particle size, huge specific surface area, strong surface adsorption, and excellent chemical purity and dispersion performance, exhibits unique advantages in reinforcement, thickening, and thixotropy. This makes it irreplaceable in many disciplines and fields. Next, let's explore the areas where nano-silicon dioxide can shine.
Application of silicon dioxide in feed

Silicon dioxide is an inorganic compound with the chemical formula SiO₂, widely found in nature and the most important compound of silicon.
The role of silicon dioxide in rubber
2025-03-27
Silica in rubber primarily acts as a reinforcing agent, significantly improving the physical and mechanical properties of rubber and is widely used in various rubber products.
What is the function of silica in rubber?
2025-03-27
In rubber products, silica has a number of important functions. Firstly, silica can significantly improve the physical properties of rubber products, including hardness, abrasion resistance, tear resistance and tensile strength. For example, adding an appropriate amount of silica to silicone rubber can significantly improve its strength, increasing the tensile strength of the vulcanized rubber to 14 MPa, demonstrating a significant reinforcing effect.
