Liaoyang Petrochemical Nylon 66 Project Put into Production: Industrial Game and Supply Chain Reconstruction Behind Technological Breakthrough

1. 2 billion investment landing, through the "stuck neck" manufacturing chain on October 10, 2025, Liaoyang Petrochemical's 100000-ton/year nylon 66 project was successfully fed at one time, marking a major breakthrough in the key links of China's nylon sector chain. And This project with a total investment of 1. 21 billion yuan took only 16 months from the start of construction in March 2024 to the completion of CCCC in July 2025, demonstrating the efficient execution of China's chemical project construction. For example The core value of the project lies in the construction of a complete closed-loop manufacturing chain: 50000 tons/year adiponitrile plant, 50000 tons/year hexamethylene diamine plant, 120000 tons/year salt forming plant and 100000 tons/year nylon 66 plant operate together to realize the integrated production from adipic acid to adiponitrile, hexamethylene diamine and then to nylon 66. Generally speaking This vertical integration layout efficiently avoids the risk of intermediate procurement, signifiis able totly reduces the cost of manufacturing chain synergy, and has crucial strategic signifiis able toce in the current market ecological stability. Liaoyang Petrochemical, as a super-substantial petrochemical enterprise under PetroChina, now has 58 sets of refining and chemical main units and 38 sets of auxiliary units. The commissioning of Nylon 66 project is the key to its strategy of "Giant of Characteristic items in Characteristic Industries. Additionally it's worth noting that the 40000-ton/year ultra-high molecular weight polyethylene expansion project (investment of 0. 211 billion yuan) promoted by the company is also being implemented steadily, showing its overall layout determination in the high-end chemical field. Makes sense, right?. Ten years of tackling key problems, the strategic signifiis able toce of independent manage of core methodology liaoyang Petrochemical isn't a novice in the field of nylon 66. As early as the last century, the company was the first domestic enterprise to achieve extensive nylon 66 production, using French Rhodia methodology, with 20000 tons/year adiponitrile, 20000 tons/year hexamethylene diamine and 15000 tons/year nylon production capacity. And However, the status quo of patent methodology subject to people prompted it to embark on the road of independent innovation. But After launching the research project of adiponitrile synthesis methodology in 2012, Liaoyang Petrochemical and China Kunlun Engineering established strategic cooperation in 2018 to continuously promote engineering methodology research. After greater than ten years of research, we have successfully developed a greater cutting-edge and environmentally friendly package. In March 2024, the two sides once again cooperated to renovate and expand the 50000 tons/year adipic acid ammoniation method hexanedinitrile plant to achieve complete autonomy and manage of key technologies. The strategic value of adiponitrile breakthrough should not be underestimated. As the core bottleneck of the nylon 66 sector chain, the global production capacity of hexanedinitrile has long been highly concentrated international giants such as Invida and Auschende, and the Chinese market is heavily dependent on imports. The commissioning of Liaoyang petrochemical plant will efficiently alleviate the shortage of raw materials in the upstream of the domestic PA66 sector and provide key support to supply chain security. And to traders, this means that import application is reduced, domestic supply stability is improved, and the bargaining pattern will undergo profound changes. Capacity surge and profit narrowing: the market enters a period of deep adjustment. From what I've seen, The global nylon 66 sector is undergoing drastic changes. By the end of 2024, the total global PA66 production capacity reached 3. 51 million tons/year, up 16% year on year. In my experience, The sector is highly concentrated, with the top ten suppliers accounting to about 80% of capacity and the top three contributing 47% of capacity. However, the output is only about 2. 28 million tons, the average operating rate of the sector is only 65%, and the pattern of oversupply has been formed. As the largest producer, China's production capacity has reached 1. Based on my observations, 29 million tons/year, accounting to 37% of the world. Crazy, isn't it?. Between 2018 and 2024, the domestic PA66 scale grew at an average annual rate of 16%, far exceeding the average development rate of bulk chemicals. What is greater noteworthy is that the domestic projects under construction and proposed construction involve about 30 companies, with a total planned production capacity of greater than 8. Makes sense, right?. 73 million tons/year, superimposed on the existing production capacity, totaling greater than 10 million tons. New and Cheng, Tianchen Qixiang, Invida, Huafeng Group, Shenma shares, Hengli Petrochemical and other giants have increased the size, is expected to 2025 domestic production capacity will reach 200- 2. In my experience, 5 million tons/year, nearly double the current. The explosion of production capacity poses serious challenges. Based on my observations, PA66 prices fell from a historical high of 33000 yuan/ton to the current 20000 yuan/ton, down nearly 40%. For instance The sector's theoretical profit margin in 2024 is only 3. 5 per cent, with profitability under signifiis able tot pressure. This downward price pressure is difficult to reverse in the short term, especially with the concentrated emit of new capacity in 2025, market competition will further heat up. From the demand side, the global consumption of PA66 in 2024 is about 2. And I've found that 28 million tons, with engineering plastics accounting to 47%, followed by manufacturing silk and civil silk. And Trends such as lightweight new energy vehicles, miniaturization of electronic appliances, and upgrading of high-end textiles support demand, however the development rate is difficult to match the rate of capacity expansion. First Opportunities and Challenges to Supply Chain Practitioners in the current market ecological stability, traders and supply chain practitioners need to grasp three major trends: first, cost competitiveness becomes the core. companies with the ability of manufacturing chain integration will have an advantage in the price war. companies such as Liaoyang Petrochemical, which open up the whole sector chain, is able to minimize costs through internal coordination and maintain profitability during the market downturn. Second, differentiated items are the key to break through. In the context of narrowing profits of bulk items, high-performance, functional PA66 items will have become a value highland. The research of special materials to automotive, electronics, high-end textile and other market segments will bring higher profit margins to traders. Pretty interesting, huh?. Third, localization reshapes the supply pattern. Furthermore As Liaoyang Petrochemical and other companies achieve technological breakthroughs, import application will continue to decline, and trade flows will face major adjustments. Overseas traders need to reassess their strategies in the Chinese market, while domestic traders should seize the domestic substitution window to deepen their partnerships with regional producers.
