Silicone is a synthetic polymer with a structure mainly composed of silicon atoms and oxygen atoms. Since the silicon-oxygen bond constituting the main chain has a high bond energy, the stability of the silicone polymer to heat and oxygen is much higher than that of a general organic polymer. Although the mechanical properties of silicone at room temperature are not much different from other materials, it exhibits excellent physical and mechanical properties at high and low temperatures, alternating between minus 60 and 250 degrees Celsius. Performance is not affected, and some can even be used normally at minus one hundred degrees Celsius; with high temperature resistance, electrical insulation, ozone resistance, radiation resistance, flame retardancy, water repellency, corrosion resistance, non-toxic and tasteless, and physiological inertia. Today, silicones are widely used in electrical, electronics, construction, textile, light industry, medical and other industries, and have a wide range of applications in the automotive industry.
