HUAFON GROUP Adipic Acid: A Global Leader in High-Purity Adipic Acid Production

Adipic acid is one of the most important aliphatic dicarboxylic acids used in modern industry. As a key intermediate connecting upstream petrochemical feedstocks with downstream polymer materials, it plays an essential role in the production of engineering plastics, polyurethanes, biodegradable materials, and various specialty chemicals. Among global adipic acid producers, HUAFON GROUP has established itself as one of the world's leading manufacturers through its subsidiary, Chongqing Huafon Chemical Co., Ltd., supported by large-scale production capacity and an integrated industrial chain.

The primary production base for HUAFON GROUP's adipic acid is Chongqing Huafon Chemical Co., Ltd., located in the Baitao Chemical Industrial Park in Fuling District, Chongqing, China. Following the successful commissioning of its expansion project in 2024, the company's total designed adipic acid production capacity reached approximately 1.355 million metric tons per year. With this scale, HUAFON accounts for approximately 45% of China's adipic acid market and around 32% of global production capacity, making it one of the largest adipic acid manufacturing bases in the world.

HUAFON's adipic acid has been recognized as a National Manufacturing Single Champion Product in China. Its manufacturing system complies with multiple international management standards, including ISO quality, environmental, and occupational health and safety management systems. The production facility has also been recognized as a National Green Factory and a National Intelligent Manufacturing Demonstration Factory, reflecting the company's long-term commitment to sustainable and advanced manufacturing.

HUAFON supplies high-purity adipic acid in the form of white crystalline powder. The product is slightly soluble in water while readily dissolving in alcohols, ethers, and many organic solvents. Stable purity and consistent quality allow it to satisfy the raw material requirements of a wide range of downstream industries.

The company primarily adopts the cyclohexene process for adipic acid production. Compared with conventional manufacturing routes, this technology offers lower energy consumption and reduced emissions. The facility is also equipped with nitrous oxide (N₂O) emission reduction systems that help minimize greenhouse gas emissions during production, supporting low-carbon manufacturing objectives. Combined with self-owned energy infrastructure and convenient Yangtze River transportation, HUAFON benefits from strong cost competitiveness and reliable large-scale production capabilities.

The broad application portfolio of adipic acid forms the foundation of HUAFON's business growth.

Its largest application is the production of Nylon 66 through polymerization with hexamethylenediamine. Nylon 66 engineering plastics and fibers are widely used in automotive lightweight components, railway transportation, industrial machinery, electrical equipment, textiles, and engineering applications.

Adipic acid is also an important raw material for polyester polyols, which are further used in polyurethane dispersions, thermoplastic polyurethane (TPU), synthetic leather, elastomers, adhesives, sealants, and footwear materials.

In recent years, adipic acid has become one of the essential raw materials for PBAT biodegradable plastics. As global demand for environmentally friendly packaging and sustainable materials continues to increase, this application segment is expected to remain an important growth driver for adipic acid consumption.

Beyond polymer materials, adipic acid is widely utilized in the manufacture of ester plasticizers, high-performance lubricants, pharmaceutical intermediates, coating additives, adhesives, and numerous specialty chemical products.

Supported by HUAFON GROUP's vertically integrated industrial chain, the company's adipic acid business maintains a balanced sales structure combining internal consumption, domestic distribution, and international exports.

Part of the production capacity is consumed internally by the group's downstream polyurethane and spandex businesses, creating stable integration across the value chain. Externally, HUAFON supplies numerous polymer manufacturers throughout China while exporting adipic acid to more than 30 countries and regions, including Japan, South Korea, Southeast Asia, and Europe.

The company primarily serves end-use manufacturers directly and can provide different product grades, customized packaging solutions, and flexible logistics arrangements to meet diverse customer requirements while ensuring long-term supply stability.

Within China's adipic acid industry, production capacity is concentrated among several major manufacturers. HUAFON continues to maintain a competitive market position through its advantages in production scale, manufacturing technology, geographic location, and integrated industrial operations.

Looking ahead, long-term demand for adipic acid is expected to benefit from several industry trends, including the localization of the Nylon 66 supply chain, the expansion of biodegradable plastics, and continuous growth in polyurethane applications. Nevertheless, the industry also remains subject to cyclical fluctuations driven by upstream raw material prices, such as benzene and nitric acid, as well as broader manufacturing activity.

To support future development, HUAFON continues to invest in process optimization, energy-saving technologies, and digital manufacturing systems to further improve product consistency, operational efficiency, and resource utilization. Leveraging its adipic acid production advantages, the company is also expanding its presence across upstream and downstream advanced materials, strengthening the integration from basic chemical intermediates to high-performance polymer products.

As one of China's leading chemical manufacturers, HUAFON GROUP's adipic acid business demonstrates the country's continued progress toward large-scale, sustainable, and internationally competitive production of essential organic chemical intermediates.
