On July 8th, the reporter learned from the video conference of new chemical materials work of China Petroleum Refining and Chemical Company that the new material business of Dushanzi Petrochemical Company has developed rapidly thanks to the two-level "leading group+business division" working mechanism of new energy and new materials of refining and chemical company and regional company. In the first six months of this year, the company's output of new chemical materials reached 192,000 tons, ranking first among China's petroleum refining and chemical enterprises.

Du Petrochemical Company strengthened the research and development of new materials, focusing on the development of new materials such as high-end polyolefin and high-performance green rubber, and focused on developing the production technology of solution polymerized styrene-butadiene rubber. On March 10th this year, the newly-built 60,000-ton solution polymerized styrene-butadiene rubber production line of Dushi Petrochemical Company was officially put into production. Immediately, the company organized the long-term research activities of new production lines, and one of the production lines realized long-term operation after the first start-up, which ensured the high output of the production lines. Up to July 1st, two production lines of solution polymerized styrene-butadiene rubber produced 49,000 tons of SSBR2557S and SSBR2564S.

Independent Petrochemical Company increased its investment in science and technology, enhanced its independent research and development capability, solved key core technical problems, improved and strengthened the construction of scientific and technological innovation system, and built an innovative enterprise of the group company. In the first half of this year, by optimizing the control procedure of catalyst dilution in high-density polyethylene plant, the company completely solved the problem of catalyst blockage during the dilution of chromium-based catalyst, and avoided large production fluctuation in the plant. Production of high-end products in the field of thin film capacitor film, successfully replacing imported products; Completed the trial production task of producing titanium-based high-density rolling plastics with domestic catalyst, and enriched polyethylene line products.

At present, Dushi Petrochemical Co., Ltd. can produce metallocene film, solution polymerized styrene-butadiene rubber, polystyrene, rare earth butadiene rubber and other new materials of many brands. The company is the first enterprise in China to realize the large-scale and serialized stable production of metallocene polyethylene film special materials, and some products can realize the equivalent substitution of imported similar products. Environment-friendly solution polymerized styrene-butadiene rubber (SBR) filled the technical gap in China and realized the localization of tire core materials. Not long ago, solution polymerized styrene-butadiene rubber was selected as the innovative product of new chemical materials of China Petroleum and Chemical Industry Federation in 2021.

In the first half of this year, Dushi Petrochemical has completed the trial production of five of the eight new brand products planned for the whole year, and a number of key high-end and efficient products have achieved breakthroughs in promotion. The sales volume of new chemical materials of the company reached 136,000 tons, exceeding the target of 41,000 tons, among which the sales volume of polyethylene high-end pipe series products increased by more than 10,000 tons year-on-year, achieving stable application in the field of gas pipes.
