Silicone, known as "industrial MONOsodium glutamate", English name: silicone, that is, silicone compound, refers to the compound containing Si-O bond, and at least one organic group is directly connected with the silicon atom, is also used to those through oxygen, sulfur, nitrogen, such as the organic group and silicon atom connected to the compound is also regarded as silicone compound. With silica, among them the key (- Si - 0 - Si -) as the skeleton of polysiloxane, is the largest organic silicon compounds, and studies the deepest, the most widely used type of account for about 90% of the total amount above, other polymeric materials because of its incomparable unique properties, such as: high and low temperature, moisture, insulation resistance, corrosion resistance, ageing resistance and physiological inertia etc.

Simply put, the most basic raw materials of organic silicon are three kinds: Silicon metal, methanol and hydrogen chloride, and let the methanol react with hydrogen chloride to form CH3Cl, and then let the silicon react with CH3Cl, The main products obtained are methyl trichlorosilane (SiCH3Cl3), dimethyl dichlorosilane (Si(CH3)2Cl2), trimethyl chlorosilane (Si(CH3)3Cl) and tetrachlorosilane (SiCl4). These chlorosilanes are hydrolyzed to form various silanols by replacing the chlorine atom (Cl) in the chlorosilane with an hydroxyl group (OH). These hydroxyl groups are reactive, and their reactivity combined with the four-directional nature of the silicon atoms makes the organosilicon so versatile. Its downstream silicone products, mainly silicone rubber (room temperature vulcanizate and high temperature vulcanizate), silicone oil, silicone resin, silicon coupling agent and other four categories, up to 10,000. In addition, the monomer by-product of silicone production process can also be gas phase silica, which not only solves the problem of tail gas treatment, but also realizes the effective utilization of resources.

Silicone with Si-O bond as the main chain structure, side chain through silicon atoms and other various organic groups connected, in addition, silicone product structure contains both "organic group" and "inorganic structure". And the bond energy of si-O bond in silicone is much greater than that of C-C bond, so the thermal stability of silicone products is high, and the chemical bond of molecules is not broken and decomposed at high temperature (or radiation irradiation). So it can withstand high and low temperature, can be used in a wide temperature range; At the same time, there is no double bond in the main chain, which is not easily decomposed by ultraviolet light and ozone. The special composition and molecular structure of organosilicon materials combine the functions of organic and inorganic materials, and have excellent high and low temperature resistance, weather resistance, electrical insulation, biocompatibility and so on. Silicone materials have been widely used in construction, electronics, electrical, chemical and other civil aspects, and even in aviation, cutting-edge technology, military technology sector and other fields. Such as the extreme conditions of outer space, the extreme cold of Siberia or the extreme heat of the Sahara Desert can show excellent characteristics.
