About 45% of nylon 66 is used in the automotive industry, and about 16% is used in the electrical and electronic industry. As the penetration rate of new energy vehicles increases, the trend toward lighter vehicles becomes more evident. As an engineering plastic material, nylon 66 offers advantages such as light weight, heat resistance, oil resistance, and flame retardancy, making it an ideal alternative to traditional metal materials. It can be widely used in automotive engine systems, electrical systems, chassis systems, etc., showing great potential for replacing metals with plastics. For new energy vehicles, every 100 Kg reduction in weight increases the range by 10%-11%, while reducing battery costs and operational expenses by 20%; the advantages of weight reduction are significant. As \"carbon neutrality\" continues to advance in the future, there remains significant room for growth in demand for PA66 in sectors such as automobiles and consumer electronics. In recent years, with advancements in domestic hexanitrocellulose technology, nylon 66 materials are experiencing a period of rapid development. More and more companies are beginning to invest in the nylon 66 industry. According to incomplete statistics, the main domestic companies involved in this sector include Shenma Shares, Jiuyuan Chemical, Longhua New Materials, Tianchen Qixiang, Xinhecheng, Xuyang Tianchen, Rongsheng, etc. The production capacity in this field is set to exceed 10 million tons in the future. As one of the most widely used nylon products, nylon 66 is utilized extensively in areas such as engineering plastics, industrial fibers, and consumer fibers, thanks to its high strength, good wear resistance, and excellent lubricating properties. From the perspective of downstream markets, relevant statistics show that approximately 59% of global nylon 66 consumption is used in engineering plastics, while 41% is used in synthetic fibers.
The new production capacity is on its way. On November 26, according to a statement issued by the Fuyang Municipal People’s Government, the second phase of the project undertaken by Haoyuan Chemical Group, which involves an investment of nearly 12 billion yuan and aims to produce 400,000 tons of nylon 66 per year, will soon begin construction, with a capacity of 50,000 tons per year. On August 20, 2024, the first batch of nylon 66 pellets was successfully produced by Anhui Haoyuan Chemical Group Co., Ltd.’s 400,000-ton-per-year nylon 66 production project (Phase I), marking the successful commissioning of the project and its official entry into operation. Previously, Haoyuan Chemical Group said that the project for producing 400,000 tons per year of high-end nylon 66 materials was scheduled to go into operation in August next year. The construction of the 400,000-ton capacity high-end nylon 66 new material facility includes a 270,000-ton/year nitric acid plant, a 240,000-ton/year cyclohexanol plant, a 320,000-ton/year adipic acid plant, a 400,000-ton/year nylon 66 polymerization plant, as well as various supporting facilities; of this amount, the 270,000 tons of nitric acid produced annually are used entirely for the production of adipic acid. The 240,000 tons per year of cyclohexanol is also entirely used for the production of adipic acid. Of the 320,000 tons of adipic acid produced annually, 260,000 tons are used as raw material for nylon 66, while 60,000 tons are sold as a finished product. All 400,000 tons of nylon 66 were sold externally. On November 25, the Putian City Ecology and Environment Bureau issued its approval comments on the environmental impact assessment report for Project Phase I of Fujian Rongchuang High-Performance Materials Co., Ltd., which involves the production of 400,000 tons per year of adipic acid and 600,000 tons per year of special functional materials. The product plan for the first phase of this project is an annual production capacity of 80,000 tons of nylon 66 chips; the specific construction scale of the project is one salt formation unit with an annual capacity of 100,000 tons ； 1 set of 50,000 tons/year continuous polymerization nylon 66 plant ； 1 set of a 30,000-ton/year batch polymerization nylon 66 plant. The total investment is 560 million yuan. On November 7, Shanghai Jieda Chemical Co., Ltd. and Invista Nylon Chemicals (China) Co., Ltd. signed a memorandum of cooperation. Invidia has decided to license its core nylon 66 polymerization technology to Jida, and has committed to providing a stable supply of raw materials. The Jieda Nylon 66 integrated project is a key initiative in the Shanghai Chemical Park. It serves as a crucial element in the efforts to strengthen and expand the nylon industry cluster, with the Invista Shanghai 400,000 tons per year adiponitrile production facility serving as the core of this plan. The project is located adjacent to the Invista Nylon integrated complex, with a production capacity of 120,000 tons per year of hexamethylenediamine, 120,000 tons per year of nylon 66 as well as nylon 610/612 resin flakes, and 50,000 tons per year of modified nylon 66/nylon 610/nylon 612 resin flakes. In early November, Longhua New Materials stated on its investor platform that the construction and equipment commissioning for the company’s first-phase 40,000-ton nylon 66 production project have been largely completed, and trial production is set to begin. The company will, in accordance with the progress of the project, strictly fulfill its information disclosure obligations in a timely manner in line with relevant regulations. On August 8, the expansion project of Invista’s nylon 66 polymer production facility was officially completed, bringing the facility’s annual production capacity to 400,000 tons per year. It is worth noting that this giant in the nylon industry announced on July 24 that it would invest 121 million yuan in its plant in Metland, Canada, to restart the adipic acid production facility; operations are expected to begin in the first quarter of 2025, which demonstrates Invida’s confidence in the nylon 66 market.
On August 5, the amide and nylon new material project invested 14.5 billion yuan in total by Sanning Chemical was officially put into operation. Upon full production capacity, the project will be able to produce 400,000 tons per year of caprolactam and polyamide chips, 200,000 tons per year of newly developed polyamide materials for spinning, and 200,000 tons per year of nylon 66. On the evening of July 17, Sinocell issued an investment announcement. At the board meeting held on that day, the company approved the resolution regarding external investments, agreeing to sign an Investment Cooperation Agreement with the Tianjin Economic-Technological Development Area Management Committee in order to invest in the development of a nylon new materials project in the Tianjin Nangang Industrial Zone. The total investment amount is approximately RMB 10 billion (subject to the actual investment amount incurred). The investment for the first phase of the project is approximately 3 billion yuan; utilizing technologies developed in-house by the company, a facility with an annual production capacity of 100,000 tons of adiponitrile-adipamide will be built ； Once Phase 1 of the project is put into operation, Phase 2 will be launched. The second-phase project is planned to require an investment of around 7 billion yuan; it will involve the construction of a facility with an annual production capacity of 400,000 tons of adiponitrile-adipamide. Additionally, a facility for the production of 400,000 tons of nylon 66 per year will be built as part of this project, extending its operations into the downstream materials sector. The specific details of construction and the associated investments will be determined by Party B based on market conditions. To date, there are approximately 30 companies in China involved in ongoing or planned projects for nylon 66 production, with a total capacity of over 8.73 million tons per year; when this is added to the capacity already in use, the overall capacity exceeds 10 million tons. Among them, the enterprises with larger planned production capacities include: Jiuyuan Chemical (1.2 million tons), Longhua New Materials (1.08 million tons), Tianchen Qixiang (1 million tons), and Xinhecheng (800,000 tons), among others.
