Organic silicon is a kind of artificially synthesized polymer with a silicon atom and an oxygen atom as its main chain. Because the silicon-oxygen structure constituting the main chain has a strong chemical bond, the molecules of the silicone polymer are much more stable to heat and oxygen than the general organic polymer. Although the mechanical properties of silicone at room temperature are not much different from other materials, its physical and mechanical properties are excellent at high and low temperatures. The temperature is repeatedly changed at -60 to + 250 ° C without affecting its performance. Therefore, the silicone polymer can be used for a long time in this temperature range. Some silicone polymers work better at temperatures as low as -100 ° C. Because of the dipole effect in the organic silicon molecule, it can effectively buffer and reduce the influence of external electric fields, thereby protecting the hydroxyl group connected to the silicon atom, making it less susceptible to attack by physical factors or chemical agents. Various products made of polyorganosiloxane have not only corrosion resistance, radiation resistance, high and low temperature resistance, but also low moisture absorption, high insulation resistance, low dielectric constant, low stress, vibration reduction, environmental protection, Low toxicity, flame resistance, and reworkability. As a result, silicones are made into a variety of finished products such as adhesive sealants, potting compounds, insulating coatings and silicone greases for use in various electronic devices.
