On April 24th, Jilin Petrochemical received a good news from the 200t/y ethylene propylene rubber pilot plant: 100# unit and 200# unit successfully completed the hexane test, and 300# unit and 400# unit successfully completed the test of the real material. At this point, the device was successfully completed. The entire process flowed through, indicating that the project has entered a substantive stage of research.
Wang Gang, director of the Rubber Research Institute of Jilin Petrochemical Research Institute, said: "As the sole ethylene propylene rubber production base in the country, Jilin Petrochemical Company's products have fewer trademarks, narrow application fields, and small production capacity. The contradiction between them is becoming increasingly prominent, and it is no longer able to satisfy the rapid development of China's automobile industry. The demand for components, waterproofing membranes, wires and cables, etc., especially for high-end sealing tapes, etc. is still blank.To break the foreign blockade of high-end products, expand market share, and improve China's ethylene propylene rubber right to speak, the company Organize technical personnel to concentrate on research, speed up the pace of research and development for new grades of products, and develop the 50,000-ton/year ethylene propylene rubber process package."
At present, China's demand for synthetic rubber has been rising year by year, but domestic self-sufficiency is only about 60%. There is a huge gap in the market, especially the domestic share of ethylene propylene rubber, isoprene rubber and other varieties is less than 10%, which seriously restricts the development of downstream industries. Jilin Petrochemical is an important synthetic rubber production enterprise in China. It has unique advantages in the research and development of synthetic rubber. They accelerate the transformation of technological achievements, vigorously implement technological research, and strive to build a synthetic rubber production and R&D base with strong comprehensive strength.
"Jilin Petrochemical has continuously exerted its scientific and technological advantages and successfully developed 11 new grades of ethylene-propylene-rubber new products with a production capacity of 70,000 tons per year, forming a series of superior products of the ternary and binary series. The technical transformation of Line B is stepping up its implementation and will realize differences. Chemical development and production capacity will increase.†Zou Xiangyang, head of the ethylene propylene rubber project, said with full confidence.
Styrene-butadiene rubber products have been the key products of Jilin Petrochemical for many years. Based on the introduction of absorption and innovation, researchers have successfully developed a new technology for rapid, high conversion milk polybutadiene-butadiene rubber, which was achieved during the “11th Five-Year Plan†period. Industrialization, with a production capacity of 140,000 tons/year. With the growing awareness of environmental protection among countries in the world, the international market has set a deadline for the use of styrene-butadiene rubber. The European Union has imposed strict restrictions on such products entering the European Union, and competitive products have also faced the test of "speed of life and death." Therefore, the development of environment-friendly styrene-butadiene rubber has become a key link in seizing market opportunities.
According to Dr. Lu Shulai, head of the environmental protection styrene-butadiene rubber project, through the unremitting efforts of scientists and technicians, since last year, Jilin Petrochemical successfully developed environmentally friendly styrene-butadiene rubber 1500E and achieved industrial production. The 1502E industrialization production has also entered a countdown, breaking the West. The country’s environmental protection barriers provide conditions for downstream tire products to go abroad. At the same time, the high-end work of styrene-butadiene rubber products is in full swing. The research and development of oil-filled rubber and nano-gel has started and will become the company's new growth pole.
Isoprene rubber is the third type of synthetic rubber that Jilin Petrochemical is advancing. The self-sufficiency ratio of China's natural rubber products is far lower than the internationally recognized 30% safety guarantee line, and its dependence on the international market is large. Isoprene rubber has become the best substitute for natural rubber because it is the closest to the natural rubber structure. At present, the Jilin Petrochemical 1000 tons pilot plant construction is in full swing, the development of technology package is steadily implemented, and the industrialization of isoprene rubber is just around the corner.
According to reports, Jilin Petrochemical pioneered the world's rare earth catalytic system isoprene rubber technology. PetroChina positioned Jilin Petrochemical as the C5 agglomeration and processing base in the three northeastern provinces and provided sufficient isoprene raw material guarantee for the industrialization of isoprene rubber. Right now, the company is assembling technology and speeding up the industrialization of isoprene. By then, a brand-new industrial chain for comprehensive utilization of C5 will be born to provide reliable support for Jilin Petrochemical to build a 100 billion yuan industrial base.
At present, through the establishment of a research, production and research alliance, the company integrates the technical advantages of Changchun Yinghua Institute and other institutes, conducts research on engineering amplification of isoprene rubber and new product development, and further refines the design, refinement process, and accumulates data. In particular, speed up the application of isoprene rubber on semi-steel radial tires. Through tests, 40 parts (quality) of Jilin Petrochemical isoprene rubber was used as a substitute for natural rubber, and good test results were obtained. It is comparable to imported products in terms of puncture-resistance performance, etc., thus filling China’s semi-steel radial tires. E-rubber blanks. The 1,000 kiloton isoprene rubber pilot plant will be tested and accepted this year, which will greatly reduce the industrialization risk of isoprene rubber technology and provide technical data for the next 10,000-ton plant construction.
