As an important general-purpose engineering plastic, polycarbonate has seen rapid consumption growth in China in recent years. The annual consumption has rapidly increased from 150,000 tons in 2000 to 590,000 tons in 2004. From 1995 to 2004, the average growth rate of polycarbonate consumption in China reached more than 30%. However, due to the serious shortage of domestic polycarbonate production, there is no large-scale production capacity, and it is necessary to make up for it by relying on large amounts of imports each year. The contradiction between supply and demand is very prominent. Therefore, it is imminent to accelerate the development of China's polycarbonate industry.
Domestic production is almost blank China's polycarbonate research and development started very early. The Shenyang Research Institute of Chemical Industry began research and development of polycarbonate as early as 1959, but it has not yet formed scale production in more than 40 years. In 2004, only eight plants including Shanghai Zhonglian Chemical Plant, Chongqing Changfeng Chemical Plant and China Minmetals Changzhou Synthetic Chemical Plant had production facilities. However, the scale of the plant is relatively small, the production technology is relatively backward, the output is low, and the product grade is small. The total annual production capacity is only about 5,000 tons, and the actual output is only about 3,000 tons. And because the quality can not meet the requirements of downstream application manufacturers, most of the products are for their own use. Therefore, for a long time, almost all of the supply of polycarbonate in the domestic market has been solved by imports. In 2004, China's polycarbonate imports have rapidly increased from 266,000 tons in 2001 to about 59 million tons.
Demand growth momentum is full In recent years, the rapid growth of China's polycarbonate market is mainly driven by the demand for electronic and electrical products, hollow sun panels, CD and DVD discs, and non-disposable drinking water drums and food containers. Its consumption structure is roughly: about 42% for electrical and electronic and computer accessories, about 26.3% for hollow solar panels, about 13.1% for CDs and DVDs, and about 10.5% for drinking water drums and food containers. About 9.1% of the composite materials and automotive industries and other fields. In the next few years, China’s original main consumption areas will continue to maintain rapid growth, and computer and home appliances will continue to grow. The average annual growth rate of polycarbonate in this area will be approximately 10% to 12%; railways, highways, airports And urban construction, the demand for hollowed out solar panels is still strong. It is estimated that the average annual growth rate of polycarbonate demand will be around 12% to 15% in the future; at present, China has become the second largest CD consumer in the world, with Bayer Corporation in Shanghai. CD-grade polycarbonate is put into production. In the next few years, the demand for polycarbonate on optical discs will continue to grow at a high rate of over 20%. In the future, the fastest growing demand for polycarbonate in the country will be the use of a mixture of gold as a base material. Composite materials, of which the automotive industry will be the main driving force.
Investment Enthusiasm Still Difficult to Compensate To ease the domestic supply-demand conflict, foreign investors have accelerated their investment in the Chinese polycarbonate market. Bayer has formed a joint venture with Shanghai Huayi Group to jointly invest US$560 million in the construction of a polycarbonate plant in the Shanghai Chemical Industry Park. The first phase of the project is planned to be completed in the second quarter of 2006 with a production scale of 100,000 tons. The second phase of the project will be completed. Gradually expand the production scale to 200,000 tons (predicted from 2007 to 2008); Teijin Chemical Corporation is building a 50,000-ton/year polycarbonate unit in Jiaxing, China, which will be put into production in June 2005 and is expected to expand in 2007. 50,000 tons / year; In addition, Mitsubishi Gas Chemical Corporation also plans to build 100,000 tons / year polycarbonate plant in China, if approved for production in 2007 is expected.
With the successful development of a new continuous polycondensation process of polycarbonate with 10,000-ton transesterification in China, the gap between China's polycarbonate production technology and Western developed countries has been greatly shortened, and a 10,000-ton-class polytec for the use of independent intellectual property technology in China has been established. The carbonate production plant laid the foundation. At the end of March 2004, the National High-tech Industrialization Polycarbonate Project was started in Mianyang National Science and Education Pioneer Park in Sichuan Province. The total investment of the project invested by Chenguang Development Industrial Co., Ltd. reached 2 billion yuan, and eventually the annual production capacity will be formed. 50,000 tons, of which an annual production capacity of 10,000 tons will be put into production in 2005; Bluestar plans to introduce technology to build a 20,000-ton/year polycarbonate plant in Lanzhou or Nantong, and the feasibility study report has passed the review. Approval is being filed; Jilin Chemical plans to build a 100,000-ton/year polycarbonate plant in 2007; Lanzhou Chemical Plant will also invest 1.538 billion yuan to build a 100,000-ton/year polycarbonate plant.
It is expected that the annual average growth rate of demand for polycarbonate in China will remain between 15% and 20% in the next few years, and the demand for domestic polycarbonate market will reach about 670,000 tons and 800,000 tons in 2005 and 2006, respectively. The domestic production capacity cannot meet the domestic market demand in the short term. Even if all the proposed new plans are put into production, the demand gap for polycarbonate in China will still be large before 2010, and it will also be imported from abroad.
