Hydrated Silica Powder For Silicone Rubber

                                                      Hydrated Silica Powder for Silicone Rubber  

The precipitation method of silicon dioxide is a commonly used technique in the production of silicone rubber. This process involves the reaction of sodium silicate and an acid, resulting in the formation of silicon dioxide particles.

The main function of silicon dioxide in silicone rubber is to act as a reinforcing filler. These particles increase the strength, durability, and elasticity of the material. Additionally, silicon dioxide helps to improve the heat resistance, chemical resistance, and electrical insulation properties of the rubber.

One of the unique characteristics of silicon dioxide is its high surface area. This property allows the particles to interact more effectively with the polymer molecules, resulting in better dispersion and a stronger molecular network. This high surface area also contributes to the excellent reinforcing properties of the material.

Another important characteristic of silicon dioxide is its low coefficient of thermal expansion. This property ensures that the material remains stable and does not deform or break down when exposed to changes in temperature. This is particularly important in applications where the material is exposed to extreme heat or cold, such as in automotive or aerospace industries.

Overall, the use of precipitation method silicon dioxide in silicone rubber has proven to be a reliable and effective method of improving the quality and performance of the material. Its unique properties make it an ideal choice for a wide range of applications, from electrical insulation to automotive gaskets and seals.
