In 2023, the 400,000 tons/year monomer project of Hesheng Silicon's Shanshan plant (the total capacity of Hesheng Silicon's organosilicone methyl monomer has reached 1.73 million tons), 50,000 tons/year of Xin'an and 100,000 tons/year of Dongyue's organosilicone methyl monomer technological transformation have been completed and put into production. According to statistics, by the end of 2023, China's organosilicon methyl monomer production capacity reached 5.48 million tons, a year-on-year growth of 10%, accounting for about 70% of the global organosilicon methyl monomer production capacity.

At present, there are 13 silicone monomer enterprises in China (including foreign enterprises), Aiken Starfire (200,000 tons/year monomer project), Xingfa Group Yichang Xiaoting plant (400,000 tons/year monomer project), Sanyou Chemical (200,000 tons/year monomer project), Zhejiang Zhongtian (200,000 tons/year monomer project), Lusi Chemical (400,000 tons/year monomer project) and Dongyue Silicon Materials 100,000 tons of technology and other 6 Enterprises are in the new construction, expansion, technological transformation, involving silicone monomer production capacity of about 1.5 million tons / year; In addition, according to public information reports, there are 16 companies proposed to build silicone monomer device, involving silicone monomer production capacity of about 6.95 million tons / year, of which the new entrants proposed to build a new silicone monomer device of about 3.75 million tons / year.

At present, it is basically certain that the existing silicone enterprises will be in the next three years, the new monomer capacity of about 1.5 million tons / year. Announcement of the proposed new organosilicon monomer enterprises, only Xinjiang New Sheng'an Silicon Industry (200,000 tons / year) Technology Co., Ltd. and the engineering company signed a general contract, the rest of the company are not substantial progress, it is estimated that the "14th Five-Year Plan" period is unlikely to be completed. Due to the higher cost of silicone monomer production by overseas enterprises, the possibility of foreign silicone monomer production capacity expansion in recent years is extremely small, and there are successive withdrawal of the possibility of the "14th Five-Year Plan" is expected at the end of China's domestic silicone monomer production capacity of more than 7 million tons / year, accounting for about 75% of the global organosilicon methyl monomer production capacity.

According to "China Fluorosilicon Industry Operation Briefing (Issue 135)", in 2023, due to the "scar effect" left by the new crown epidemic and Russia-Ukraine, Palestine-Israel geopolitical conflicts, inflation, trade friction, the Federal Reserve interest rate hike and other factors, China's exports of primary forms of polysiloxanes from 45.3 million tons in 2022 to 406.5 thousand tons; the net amount of polysiloxane will be reduced to 406.5 thousand tons. Reduced to 406,500 tons; net exports from 356,300 tons in 2022 to 303,700 tons, compared with a decrease of 14.5%; Although the apparent consumption of polymethylsiloxane in the Chinese market in 2023 increased by 12% year-on-year (about 1,876,900 tons), but due to the successive and rapid release of the production capacity of China's silicone monomers in recent years, China's organosilicon monomer driving in 2023 rate from 85% in 2022 to about 77%, a decrease of about 8 percentage points from 2022. China's silicone monomer overcapacity has been highlighted!
