The basic structural unit of an organic silica gel product is composed of silicon-oxygen chains, and the side chain is connected to various other organic groups through silicon atoms. Therefore, the structure of silicone products contains both "organic groups" and "inorganic structures". This special composition and molecular structure make it combine the characteristics of organic matter with the function of inorganic matter. Compared with other high molecular materials, the most outstanding properties of silicone products are the following functions:
Temperature resistance

Silicone products have a silicon-oxygen (Si-O) bond as the main chain structure. The bond energy of the C-C bond is 82.6 kcal / g molecule, and the bond energy of the Si-O bond is 121 kcal / Gram molecules, so the thermal stability of the organic silicon is high, the chemical bonds of the molecules under high temperature (or radiation exposure) do not break, do not decompose. Silicone rubber products are not only resistant to high temperatures but also low temperatures, and can be used over a wide temperature range. Whether it is chemical or physical mechanical properties, the change with temperature is small.
Weatherability

The main chain of silica gel is -Si-O-, and there is no double bond, so it is not easily decomposed by ultraviolet light and ozone. It has better thermal stability than other polymer materials, as well as radiation and weather resistance. Therefore, the service life of many silicone parts and silicone electronic accessories in natural environments can reach decades.

Electrical insulation performance

Silicone products have good electrical insulation properties. Their dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity are among the best in insulating materials, and their electrical properties are affected by temperature and frequency. The impact is small. Therefore, they are a stable electrical insulation material and are widely used in the electronics and electrical industries. In addition to excellent heat resistance, silicones also have excellent water repellency, which is a guarantee of high reliability for electrical equipment in wet conditions.
