China has become a big consumer of silicone materials. Due to the massive export of textiles, electronics, electrical appliances and the strong demand for silicone materials in domestic construction, textile, automotive, daily chemical and other industries, it has promoted and promoted the development of silicone materials in China. In 2010, China's silicone consumption reached 555,000 tons, accounting for 36% of the global total, and it became the world's largest consumer of silicones; China's industrial structure dominated by processing and manufacturing has caused China's silicone consumption structure and other global Countries and regions are very different. In other countries and regions, the proportion of silicone rubber and silicone oil is average. China mainly uses silicone rubber.
During the "Twelfth Five-Year Plan" period, the average annual growth rate of silicone consumption in China is expected to remain at around 18%. In 2015, silicone consumption is expected to reach about 1.3 million tons, equivalent to about 2.6 million tons of silicone monomers. In 2010, China's production volume of silicone (folded siloxane) was about 410,000 tons; consumption was 555,000 tons. On the one hand, organic silicon continues to grow steadily in traditional application fields, on the other hand, it continuously develops new uses in new energy, energy saving and environmental protection, medical health and high-end manufacturing, especially in solar cells, LEDs, personal care products, and rails. In transportation and alternative petroleum-based products, its application has developed rapidly. Due to its vast market space, silicone has been included in the new material “12th Five-Year Plan”. More than 20 silicone products have been included in the product catalogue of the “Twelfth Five-Year Plan” for new materials.
The “12th Five-Year Plan” of silicones will strictly control the entry threshold and control the growth of production capacity. In 2015, the production capacity will reach 3 million tons, meeting the domestic demand and exporting slightly. The plan proposes that by 2015, there will be 3-5 organic silicon monomer backbone enterprises with international competitiveness. The plan shows that silane coupling agents should be built into 2-3 enterprises with a scale of more than 30,000 tons / year and produced with green environmental protection technology. In 2015, the total output reached 400,000 tons and the number of varieties exceeded 100.
The plant purification of bioactive silicones is currently only controlled by developed countries such as France. The important role of organosilicon on organisms makes organosilicon products have huge application prospects. In the next few years, organosilicon products using plant active extraction will expand explosively in the fields of medicine, beauty, health care and other fields.
The consumption ratio of silicone products in various industries depends on the industrial structure at that time. Taking Japan as an example, the distribution in 1988 is: electronic appliances account for about 25% -30%, construction accounts for 15% -20%, automobiles account for 10% -15%, food and medical services account for 10%, office machinery accounts for 10%, and the rest (Including fiber, paper, plastic, paint, etc.) accounted for 15% -30%. It can be seen that electronic appliances, construction and automobiles are the three pillars of the country's silicone market. In recent years, the market development trend, the development speed of electronic and electrical still ranks first, the reliability and durability of silicone materials, so that its application in the construction and automotive industries can continue to grow; due to the physiological inertness of siloxane and The safety and reliability of the human body have been further confirmed, so the number of applications of silicones in medical and cosmetics has increased dramatically.
The development of silicon
In 2011, China's industrial silicon output was 1.36 million tons, a year-on-year increase of 15.2%. The industry achieved product sales revenue of 39.201 billion yuan, a year-on-year increase of 46.43%. Since 2008, the average annual growth rate has exceeded 20%, and the total profit has reached 3.352 billion. Yuan, an increase of 77.05% year-on-year. From January to June 2012, the number of enterprises in China's silicone industry was 305, an increase of 19.61% over the same period last year; the number of employees was 65,300, an increase of 19.03% over the same period last year.
In terms of operating scale, in the first half of 2012, the industry's asset scale was 32.445 billion yuan, a year-on-year increase of 34.42%, sales revenue of 28.395 billion yuan, an increase of 56.98% year-on-year, and a total industrial output value of 28.897 billion yuan. From the point of view of operating efficiency, in the first half of 2012, the silicone industry achieved a sales profit of 2.862 billion yuan, an increase of 27.20% year-on-year, and a total profit of 1.544 billion yuan, a decrease of 1.87% from the same period last year. Overall, the overall operation of China's silicone industry in the first half of 2012 was relatively good, with rapid growth in assets and production and sales.
Judging from the consumption of silicones, the data shows that the domestic consumption of industrial silicon in China totaled 610,000 tons in 2011, a year-on-year increase of 27.1%, of which the consumption of silicones accounted for 32.79%, a decrease of 3.67 percentage points from the previous year. The consumption of castings has also decreased, while the consumption of polysilicon metal silicon has increased substantially by nearly 10 percentage points.
From the perspective of imports and exports, customs statistics show that China's industrial silicon exports in 2011 were 541,000 tons, a year-on-year decrease of 5.8%. Among them, exports to Japan were 161,000 tons, down 4.7% year-on-year; exports to South Korea 96,000 tons, up 24.6% year-on-year; exports to Europe were 98,000 tons, down 14.1% year-on-year, and total imports and exports were USD 1.075 billion, of which imports were 779 million US dollar, the export value is 295 million US dollars, the trade deficit is 484 million US dollars, and the trade gap has narrowed year-on-year ;; From January to May 2012, the cumulative export volume of domestic industrial silicon was 187,400 tons, of which the largest export volume was Japan. 61,500 tons, accounting for 32.8% of total exports; followed by South Korea, exports accounted for 14.7%; total exports of the top ten countries accounted for 76% of total exports. In recent years and for a long period of time in the future, the strongest demand for silicones will come from Asia. The growth center of demand will be China and the Pacific region. The average annual growth rate is expected to reach 10% -15%. , Construction, machinery, metallurgy, automotive, chemical, textile, medical and other industries, the consumption of silicone in China will still grow at a growth rate of more than 20% and become the fastest growing market in the world.
After 20 years of independent development and construction, the silicone industry in China has made remarkable achievements. Both the production scale of methyl chlorosilane monomer and the application technology of silicone products have made great progress.
In recent years, China's silicone market is the fastest growing market in the world. The development speed of the silicone market is higher than the GDP growth rate by more than 25%. The scale of domestic silicone monomers has developed rapidly. In 1999, only 20,000 tons / year of new materials were put into operation, and the monomer units put into production in the second half of 2007 have reached 100,000 tons / year. By 2008, China has formed five organic silicon monomer production enterprises with Blue Star Fire, Xin'an Group, Jihua Group, Meilan Group, Jiangsu Zhenjiang Hongda, with an annual production capacity of 400,000 tons. The capacity of silicones under construction in China is about 350,000 tons, and 800,000-1 million tons are planned. China's silicone deep processing and its application are forming a group of enterprises and industrial groups with high temperature adhesives, liquid silicone rubber, textile additives, silane coupling agents, etc., which are active in domestic and foreign markets. On the other hand, in recent years, the domestic silicone gap is still very large, and the import dependence rate in 2007 was about 50%.
It is estimated that the production capacity of domestic silicone companies will reach 1.2 million tons per year by 2010, and the combined production capacity of 400,000 tons per year in a joint venture between Dow Corning and Wacker in Zhangjiagang, Jiangsu, will reach 1.6 million tons per year. But in the next 3-5 years, China's silicone consumption will still maintain a growth of about 25%. Before 2010, the self-sufficiency rate of domestic silicone monomers will remain at a low level. After 2009, China's silicone industry will enter a concentrated period of production capacity release. It is estimated that China will add about 200,000 tons of organic silicon monomer in 2009. However, the total domestic demand for monomers is about 960,000 tons, and the degree of external dependence is still more than 50%.
