Weunite: Deeply Cultivating Aromatic Nitrile New Materials, Leading Green Chemical Transformation with Technology

In the Xinyi Chemical Industrial Park, Jiangsu Province, a technology-driven fine chemical enterprise is steadily advancing towards a new phase of high-quality development. Since its establishment in 2006, Jiangsu Weunite Fine Chemical Co., Ltd., through its persistent dedication to the field of aromatic nitrile new materials, has grown into a National High-Tech Enterprise, a provincial "Specialized and Sophisticated" "Little Giant," and ranked 63rd among the Top 100 Pesticide Sales Enterprises in China in 2024.

Rooted in Xinyi, Consolidating the Industrial Foundation

Jiangsu Weunite Fine Chemical Co., Ltd. was established in December 2006 with a registered capital of RMB 50 million. Located in the Xinyi Chemical Industrial Park, the company covers an area of approximately 350 mu (about 23.3 hectares) and currently employs 448 people, including over 150 professional technicians. It is a Sino-foreign joint venture with investment participation from Singaporean merchants and is now a nationally designated manufacturer of pesticide technical materials.

As China's largest green chemical enterprise that utilizes aromatics, methyl heterocycles, and other compounds as raw materials, and relies on advanced technologies such as continuous air ammoxidation, gas-phase continuous chlorination, fluorination, and chiral resolution, Weunite possesses a provincial-level "Aromatic Nitrile Derivatives Synthesis and Application Engineering Technology Research Center" and has established comprehensive R&D and testing systems. The company has obtained certifications including the ISO integrated management system (Quality, Environment, Occupational Health and Safety), the "Integration of Informationization and Industrialization" management system, an energy management system, and Grade II standardization for work safety. It has also been honored with the title of "Green Factory" by Xuzhou City.

Focusing on Core Products, Creating Global Leadership Advantages

Weunite's product portfolio covers multiple fine chemical sectors, including aromatic nitrile new materials, pesticide technical materials and intermediates, pharmaceutical intermediates, and liquid crystal intermediates. Key products include:

• Aromatic Nitrile Series: Terephthalonitrile, Isophthalonitrile, Phthalonitrile, as well as Tetrachloroterephthalonitrile and Tetrachlorophthalonitrile. The company is the world's largest supplier of Tetrachlorophthalonitrile and Tetrachloroterephthalonitrile, and the second-largest global supplier of its leading products Chlorothalonil, DCPA (Chlorthal-dimethyl), and Metaldehyde.

• Pesticide and Intermediate Series: Chlorothalonil technical and suspension concentrate (which has passed FAO international standard certification), Chlorfenapyr, Nitenpyram, Pyridaben, and others.

• Fluorinated Fine Chemical Series: Tetrafluoroterephthalic Acid, Tetrafluoro-1,4-benzenedimethanol, Tetrafluorophthalonitrile, Bromopentafluorobenzene, and Tefluthrin, among others.

• New Materials Direction: An environmentally friendly polymer new materials project with a total investment of RMB 1.2 billion, focusing on the R&D and production of specialty high-performance materials such as poly(aryl ether nitrile)s. The first phase, a demonstration project with an annual capacity of 2,000 tons, has been completed, and some products have been launched in the market.

Technology-Driven, Forging "Little Giant" Advantages in the Industry

Weunite's core competitiveness stems from its deep technological accumulation and sustained investment in innovation. The company currently holds 48 valid patents (including 17 invention patents) and has participated in the formulation of 13 standards. Leveraging advanced technologies such as continuous air ammoxidation, gas-phase continuous chlorination, fluorination, and chiral resolution, the company has established significant technical barriers.

In recent years, the company has actively promoted "transformation, upgrading, and a second pioneering effort," targeting the fields of high-performance materials and green chemistry to comprehensively enhance its processes, equipment, automation, and digitalization levels. Its aromatic nitrile new materials project has been identified as a key advantageous pillar industry in Xinyi City, with projected annual sales revenue approaching RMB 3 billion upon full completion. The company's products are primarily supplied to well-known domestic and international customers, including Jiangsu Longdian, Shandong Rainbow, Nippon Shokubai, AMVAC (USA), and UPL (India), demonstrating the international competitiveness of "Made in China" in the fine chemical sector.

Looking to the Future

Jiangsu Weunite Fine Chemical Co., Ltd. consistently upholds the corporate spirit of "Unity, Perseverance, Professionalism, and Innovation" and adheres to the development direction of "Transformation, Upgrading, and Green Chemistry." Looking ahead, the company will continue to deepen its presence in the field of aromatic nitrile new materials, persistently expand overseas markets and extend its industrial chain. It is committed to becoming a trusted global partner in the fine chemical and new materials sectors, contributing to the advancement of China's new materials industry.
