On November 29, the 2021 China Top 500 Petroleum and Chemical Enterprises Press Conference was held online. The conference released the 2021 China Petroleum and Chemical Industry Top 500 Ranking List (comprehensive category), 2021 China Petroleum and Chemical Industry Top 500 Ranking List (independent production and operating companies), as well as the ranking list by industry. In the comprehensive list, China Petrochemical Corporation, China National Petroleum Corporation, and Hengli Group Co., Ltd. rank in the top three on the list.

 Compared with last year, the obvious change in this year's list of China's top 500 petroleum and chemical companies is that about 100 energy and basic chemical raw materials companies that have been shortlisted for more than a year have withdrawn from the list. At the same time, the same amount of fresh blood joined the list this year. For example, Hangzhou Foster Applied Materials Co., Ltd., Inner Mongolia Jiutai New Material Technology Company and other new chemical materials companies; there are also high-performance specialty rubber, fiber, electronic chemicals and other specialty chemical manufacturers.

 The structural changes of this top 500 list reflect the obvious achievements of the industry during the "Thirteenth Five-Year Plan" period in "reducing overcapacity and adjusting the structure" and demonstrate the development and progress of the industry. In addition, the top 500 chemical companies have also shown strong development resilience in terms of anti-risk capabilities, and new chemical materials companies have achieved remarkable results in building world-class companies.

 Jiangsu Shuangxing Color Plastic New Material Co., Ltd. is ranked 200th on the top 500 comprehensive list this time. As one of the top ten enterprises in the plastics industry in China's light industry, Doublestar New Materials currently has five business sectors including optical materials, new energy materials, energy-saving window film materials, information materials, and heat shrinkable materials. A few days ago, Doublestar New Materials has been successfully selected into the sixth batch of manufacturing individual champions to be recognized.

 At present, Doublestar New Materials is in the transitional period of releasing new material production capacity. The company's business focus has shifted to high-end film materials represented by optical materials, and the construction of new production lines is in full swing. In September 2021, the 1905 line of the 200 million square meter optical film high-function polyester film project of Double Star New Materials was officially put into production. This is the fourth production line completed within the year of the 200 million optical film high-function polyester film project, adding new growth points for Shuangxing New Materials to further build a million-ton new material industrial base in the Yangtze River Delta.

The technical barrier of optical film is relatively high. The base material accounts for more than 60% of the cost of optical film, and it mainly relies on imports. At present, thanks to the continuous growth of terminal electronic products such as liquid crystal displays, mobile phones, and computers, the optical film field is developing rapidly as a whole. With the release of the production capacity of the 200 million square meter optical film project in the second half of the year, Doublestar New Materials' high-end film performance will continue to increase, and the pace of localization will further accelerate.

 The report shows that the main business and operating performance of Doublestar New Materials have continued the growth trend since 2020, and the "five major sectors" continue to exert strength. In the first three quarters of 2021, the company achieved revenue of 4.241 billion yuan, a year-on-year increase of 22.26%; realized net profit of 973 million yuan attributable to the parent, a year-on-year increase of 116.1%.

 Li Shousheng, president of the China Petroleum and Chemical Industry Federation, said that the next ten years will be a critical period for my country's petroleum and chemical industry to leapfrog into a powerful country. Starting from the "14th Five-Year Plan", the development of the entire industry in the future has entered a new stage dominated by independent innovation. For the new challenges of future development, the reconstruction of new energy is entering the critical moment of "pregnancy in October". In addition, in the face of the transformation of the low-carbon economy and the new requirements of green development, the high-end breakthrough of new materials has reached an important "fighting" moment.
