Dalian High Purity Chemical Co., Ltd., located in the Jinpu New Area of Dalian City, Liaoning Province, is a national high-tech enterprise specializing in the research, development, production, and sales of fine chemicals. It operates within the chemical raw materials and chemical products manufacturing industry (C26), focusing on three core areas: electronic-grade wet electronic chemicals, specialty additives for semiconductor packaging, and environmentally friendly water treatment agents. The company has achieved full-chain integration—from laboratory R&D and pilot-scale verification to large-scale mass production. Its main products include electronic-grade isopropyl alcohol (IPA), EP-800 series epoxy diluents for semiconductor packaging, electronic-grade buffered hydrofluoric acid solutions for wafer cleaning, and industrial water treatment agents. These products are widely applied in integrated circuit (IC) manufacturing, advanced packaging, display panel cleaning, and municipal/industrial wastewater treatment. Leveraging its status as a Liaoning Provincial Enterprise Technology Center and a Dalian Municipal Postdoctoral Innovation Practice Base, the company holds 17 invention patents, including a continuous high-purity electronic-grade IPA refining process (Patent No.: ZL202110876543.2) and a key monomer synthesis technology for low-stress underfill adhesives (Patent No.: ZL202211234567.1). It has completed mass-production validation for three types of electronic-grade buffered hydrofluoric acid solutions and possesses capabilities in customized electronic chemical synthesis, precise impurity control (metal ion content in IPA ≤10 ppt, meeting SEMI C12 standard), JEDEC high-temperature/high-humidity reliability testing (EP-800 passed 1,000-hour delamination-free testing), and integrated application of water treatment system agents. The company holds a High-Tech Enterprise Certificate (GR202321000476), ISO 9001/14001/45001 integrated management system certifications, and IATF 16949 Automotive Supply Chain Quality Management System certification. It also holds a Work Safety Production License, a National Industrial Product Production License, and a Hazardous Chemicals Registration Certificate, and has completed REACH pre-registration and listing on the U.S. TSCA Inventory. Representative achievements include leading a sub-project under the Ministry of Industry and Information Technology’s “Industrial Foundation Rebuilding Project” targeting domestic substitution of specialty electronic gases and associated liquid materials; participating in the National Key R&D Program “Advanced Electronic Packaging Materials” (Project No.: 2023YFB3800123); and providing water treatment agent solutions for the upgrading and reconstruction project of Dalian West Wastewater Treatment Plant (a demonstration project designated by the Ministry of Housing and Urban-Rural Development in 2024). Its electronic-grade IPA and EP-800 series products have been approved for inclusion in the qualified supplier lists of Semiconductor Manufacturing International Corporation (SMIC) and Jiangsu Changjiang Electronics Technology Co., Ltd. (JCET). The company is registered with China Customs for import/export operations (Registration No.: 2102960123), and its products are exported to South Korea, Japan, Vietnam, and Germany, serving SK Hynix’s supporting supply chain, Sumitomo Chemical’s designated distributors, and BASF’s Asia-Pacific procurement network. Collaboration models include B2B industrial raw material supply, technology licensing, and localized engineering adaptation support.
