Organosilicon generally refers to chemical molecular materials with carbonyl groups connected to the four bonds of the silicon atom. The silicon atom has various organic groups, including methyl, ethyl, alkoxy, phenyl, etc., but currently the most important application The main chain is [Si-O-Si-O]n, and the other two groups on the silicon atom are methyl cyclosiloxanes (DMC), and the downstream accounts for more than 90%. It is also what we call organosilicon monomers in our daily life. We just need to keep in mind that silicone mainly refers to silicone DMC.

Synthesis of silicone requires silicon powder and methyl chloride synthesis, about 0.25 tons of silicon powder and 0.8 tons of methyl chloride to synthesize 1 ton of crude monomers.

What are the advantages of silicone, electrical insulation, high and low temperature resistance, heterogeneous high adhesion, water insulation are the four excellent properties of silicone. The excellent performance has brought a wide range of applications, and the traditional demand is mainly based on silicone rubber. Silicone is generally made of silicone rubber made of silicon-oxygen bond polymerization. Because of the excellent properties of silicone, it is called "industrial vitamin". Silicone downstream products are mainly silicone rubber, which are mainly used in construction and electronic appliances and other fields.

Then look at the prospects of silicone? In the future, my country will become the absolute leader in global silicone production. Due to the high cost of producing organic silicon and the fact that overseas companies are hazardous chemicals, foreign companies have withdrawn one after another in recent years and have chosen to build factories in my country. An increasingly significant absolute advantage. According to SAGSI, my country's DMC production capacity in 2019 is about 1.49 million tons/year, accounting for about 58.3% of the world's total, and will mainly contribute to the future global silicone production capacity increase.

The supply and demand of silicone has begun to improve, and the growth rate of demand will continue to increase due to the recovery of the global economy. In the future, the new production capacity will likely be quickly absorbed by the rapidly growing demand; it is expected that the prosperity will continue to rise in the next two years.
