Polycarbonate (PC) is a linear polymer molecule containing carbonic acid groups in the molecular chain. It can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. However, it is a kind of aromatic polycarbonate ester. As a high-end petrochemical products, polycarbonate is the fastest growing demand for thermoplastic materials in five engineering plastics. It has excellent performance and has been widely used in the fields of electronic appliances, sheet containers, automobile industry, medical equipment and protective equipment. To aerospace, optical components, optoelectronic information and other emerging areas.
As an important global polycarbonate market, China’s demand for polycarbonate, growth is fast, but low self-sufficiency rate (less than four percent). In recent years, the state has introduced a number of policies to encourage the construction of polycarbonate projects, scientific research units with independent intellectual property rights in the production process of polycarbonate breakthrough, domestic enterprises began to launch, the expansion of polycarbonate project.
Asian chemical consulting that the next few years, China’s polycarbonate industry will usher in the outbreak of production capacity, the external dependence of the status quo or will become history, and enter the stage of intense competition in the market. Therefore, for the domestic polycarbonate production enterprises, for the downstream emerging market application development differentiation, high-end products will be the key to enterprise survival and development.

1. Domestic companies involved in polycarbonate business, breaking the foreign monopoly
China is one of the first countries to start polycarbonate technology development and industrial production, but because of the small size of the device, the technical level is backward, poor product quality and other reasons led to the product can not compete with foreign countries. Since 2005, with the Bayer (now Kesi), Teijin, Mitsubishi and other foreign-funded enterprises began to invest in the construction of polycarbonate plant in China, China’s polycarbonate market was almost a monopoly for foreign-funded enterprises.
In recent years, domestic enterprises polycarbonate project put into operation to break the monopoly of foreign-funded enterprises.
2. China’s polycarbonate demand for high self-sufficiency rate is still low

China is a big producer of polycarbonate. As of the end of 2016, China’s polycarbonate production capacity reached 87 million tons / year, accounting for 17% of the world’s total capacity of polycarbonate (512 million tons / year).
China is the fastest growing demand for polycarbonate countries. Asian chemical consultation data show that in 2016 China’s apparent consumption of polycarbonate reached 1.725 million tons. Although China’s polycarbonate production capacity and output growth in recent years, but the external dependence has been high. In 2016, China’s polycarbonate only 60 million tons, while imports up to 131.9 million tons (net imports of 1.096 million tons), external dependence as high as 63.5%.

3. The state introduced policies to encourage and promote the development of polycarbonate industry
For the current China’s polycarbonate industry is facing a huge gap between supply and demand, imports and external dependence of the high situation, the state has introduced a series of policies to encourage the construction of polycarbonate projects to guide and promote the development of polycarbonate industry.
March 2013, the National Development and Reform Commission issued the “Industrial Structure Adjustment Guide Catalog (2011) (Amendment)”, the first category of encouragement category includes 60,000 tons / year and above non-phosgene polycarbonate production plant. June 28, 2017, the National Development and Reform Commission and the Ministry of Commerce issued a “foreign investment industry guidance directory (revised in 2017)”, which encouraged foreign investment in the industry, including 60,000 tons / year and more non-phosgene polycarbonate (PC).

2016 April release of “oil and chemical industry,” thirteen five “Development Guide” in the “thirteen” during the development of China’s petrochemical industry seven tasks, one of the new materials in the field of chemical work is to accelerate the focus Blank products of the industrialization process, the specific tasks include the promotion of PC (polycarbonate), PEEN (polyether ether nitrile) and other engineering plastics and metallocene polyethylene, metallocene polypropylene and other high-end polyolefin resin and phenyl silicone single The development of the body.
October 2016, the Ministry of Industry issued the “petrochemical and chemical industry development plan (2016 – 2020)” will be listed as a representative of high-end polycarbonate products, predicting the next few years the average annual growth rate of polycarbonate 6.7 %, 2020 demand will reach 2.3 million tons. Planning put forward in the development of new chemical materials innovation project to speed up the development of 3D printing with PC-ABS materials such as high temperature and high strength engineering plastics.

In addition, in order to improve the public awareness of polycarbonate / bisphenol A, promote the healthy and sustainable development of China’s polycarbonate industry, actively coordinate and standardize industry behavior, enhance the overall level of the industry, polycarbonate / bisphenol A China Working Group and China Synthetic Resin Supply and Marketing Association Polycarbonate Branch (CNPCA) has been established in December 2015 and June 2017.
4. Innovative polycarbonate technology to help industry development
Polycarbonate industrial production process has developed a solution of phosgene, interfacial polycondensation phosgene, transesterification melt polycondensation (transesterification) and non-phosgene exchange melt polycondensation (non-phosgene). After years of development, China has also started a breakthrough in the field of polycarbonate technology development.

5. More than one million tons of production capacity concentrated release, differentiation and high-end into the development focus
China’s strong market demand, high added value of polycarbonate, and domestic and foreign capital technology, driven by planning, new or expansion of the polycarbonate project launched in China, the total capacity of these projects total more than 200 million tons / Year, of which a number of projects are expected to be put into operation in the next few years, when there will be more than 1 million tons / year of new production capacity concentrated release.
