Silica For Food Grade Silicone Rubber
In the chemical industry, the synthesis and extraction of solid silica gel structure can be considered as a technical problem. The raw materials used by silicone rubber product manufacturers are generally solidified solid compounds. In addition to siloxane and silicon dioxide, it is also necessary to add several reinforcing agents to silicone raw materials, such as silicone resin, whose main component is silicon dioxide, which accounts for most of the reinforcing agents. One of the important auxiliary materials of food grade silica gel raw material Z is silica gel raw material, and the quality must be guaranteed first. Many silicone rubber product manufacturers need corresponding test reports before selecting and purchasing raw materials, and whether they will get corresponding requirements. Silica is one of the most important materials in solid silica gel, and its quality determines the performance of the material. Its heat resistance, temperature resistance and tensile strength are superior to ordinary silicon dioxide, so it is a high-performance material in high-temperature vulcanized silicone rubber and can meet the requirements of food grade, high transparency and high tensile property.
