Weihai Jinhong Group Co., Ltd. (威海金泓集团有限公司) is a diversified modern enterprise group headquartered in the Lingang Economic and Technological Development Zone of Weihai, Shandong Province, China. According to its official website, the group traces its origins to 1986, when it was established as the Wendeng County Chemical Materials Factory (文登县化工材料厂); in March 2009 it was restructured into Weihai Jinhong Group Co., Ltd. The company describes itself as a diversified modern enterprise group whose business segments cover basic chemical raw materials, fine chemicals, product manufacturing, new materials, new energy, battery testing, bridge testing, engine blade structural testing, aerospace, the nuclear industry, electric power, and military applications, forming a complete industrial layout. The group operates through eight controlled subsidiaries: Jinhong Polymer (金泓高分子), Jinhesi Chemical (金合思化工), Haoran Special Plastics (浩然特塑), Jinyu Environmental Protection (金钰环保), Jinhong Pipe Materials (金泓管材), Chenyuan Molecular New Materials (晨源分子新材料), Weidinghang Testing Equipment (威鼎航检测设备), and Hongtai Electronics (泓泰电子). Its product portfolio is broad and technically specialized, including PVC processing aids and foam regulators (K-385, K-415, K-418, K-618, K-618A, K-705, AS-100, K-123, K-175, K-123A, K-708, K-709, K-20P, K-20T, K-121A), PVC impact modifiers (AIM and MBS grades such as KM-355, HI-M850, HI-S800, KM-362, HI-M830), CPE (CPE130A, CPE3511, CPE135A, CM352, CM353, CM356), water treatment agents, papermaking additives, biphenol, oilfield additives, PPSU tableware under the Zhuojian Zhuokang (茁健茁康) name, polysulfone (PSU), polyethersulfone (PESU), polyetheretherketone (PEEK), ultra-high-molecular-weight polyethylene (UHMWPE) pipes and composite pipes, MPP power and communication conduits, HDPE pipes, PVC pipes, and a range of dendritic and hyperbranched polymers (PAMAM, dendritic polylysine, hyperbranched polyester, dendritic polyester CYD-T1050, etc.). The group also produces automotive components such as airbags, reversing radar, main wiring harnesses, door harnesses, engine harnesses, and high-voltage ignition lines. Jinhong emphasizes research and innovation. Its official site states that it has two national-level research platforms — a National Enterprise Technology Center and a National Postdoctoral Scientific Research Workstation — plus ten provincial-level research platforms, including a provincial dendritic and hyperbranched enterprise technology center, a provincial dendritic and hyperbranched engineering technology research center, a polysulfone engineering laboratory, and a provincial plastics demonstration engineering technology research center. It reports 185 engineering and technical personnel, including 17 with senior titles, 40 with intermediate titles, 15 with doctoral degrees, and 12 with master's degrees. The group reports 50 authorized invention patents, 59 utility model patents, 16 software copyrights, and 3 design patents, and says it has participated in the formulation or revision of 5 national and industry standards and completed more than 50 national, provincial, and municipal science and technology projects. In terms of operations, Jinhong has invested more than 30 million yuan in a smart control center of about 900 square meters that integrates DCS, SIS, GDS, fire alarm, and video surveillance systems. A 2025 company news article reports that the group's sales revenue reached 720 million yuan the previous year and that it is targeting 1 billion yuan for the current year. The same article notes that a newly developed MBS plastic processing aid entered trial production with an initial order of 1,000 tons, and that full production could reach 30,000 tons per year with an estimated additional annual sales revenue of 800 million yuan.

Weihai Jinhong Group Co., Ltd. traces its origins to 1986, when it was established as the Wendeng County Chemical Materials Factory (文登县化工材料厂) in what is now Weihai, Shandong Province. Over the following decades the enterprise expanded from basic chemical materials into fine chemicals, polymer additives, and advanced materials. In March 2009, the enterprise was restructured into Weihai Jinhong Group Co., Ltd., marking a transition to a group holding structure. During the 2010s and 2020s, Jinhong diversified into multiple business segments through controlled subsidiaries. Its official website lists eight controlled subsidiaries: Jinhong Polymer (金泓高分子), Jinhesi Chemical (金合思化工), Haoran Special Plastics (浩然特塑), Jinyu Environmental Protection (金钰环保), Jinhong Pipe Materials (金泓管材), Chenyuan Molecular New Materials (晨源分子新材料), Weidinghang Testing Equipment (威鼎航检测设备), and Hongtai Electronics (泓泰电子). This structure supports business segments covering basic chemical raw materials, fine chemicals, product manufacturing, new materials, new energy, battery testing, bridge testing, engine blade structural testing, aerospace, the nuclear industry, electric power, and military applications. The group invested heavily in research infrastructure. It reports two national-level platforms — a National Enterprise Technology Center and a National Postdoctoral Scientific Research Workstation — and ten provincial-level platforms, including a provincial dendritic and hyperbranched enterprise technology center, a provincial dendritic and hyperbranched engineering technology research center, a polysulfone engineering laboratory, and a provincial plastics demonstration engineering technology research center. It has built a smart control center of about 900 square meters, with an investment of more than 30 million yuan, integrating DCS, SIS, GDS, fire alarm, and video surveillance systems. In product development, Jinhong has pursued import substitution for high-end polymer additives. A 2025 company news article describes how a team of 15 researchers conducted more than 300 experiments over five years to develop an MBS plastic processing aid that addresses low-temperature brittleness in plastics, a market long dependent on imports. The product entered trial production with an initial order of 1,000 tons, and full production is expected to reach 30,000 tons per year, with estimated additional annual sales revenue of 800 million yuan. The article also states that the group's sales revenue reached 720 million yuan the previous year and that it is targeting 1 billion yuan for the current year. Jinhong has an international trade department and an independent factory in Singapore, and its products are exported to Europe, the United States, South Korea, Japan, and Southeast Asia.
