East County Tongyu Chemical Co., Ltd.
East County Tongyu Chemical Co., Ltd. is a chemical manufacturing company located in Cangzhou, Hebei Province, China. The firm traces its origins to 1986, when it began producing the country’s early high-temperature bolt protection agents, notably the GF-1 bolt high-temperature anti-burning agent. This innovation helped end a long-standing dependence on imported bolt protection solutions for industrial high-temperature equipment. Over the years, the company expanded its product line through collaboration with users and research departments, culminating in the development of serialized anti-burning agent products such as GR-9 and GR-12 in 1991. These products broadened the company’s application scope from petrochemical and chemical industries to rail locomotive and metallurgical sectors.
In 2006, the company developed and produced higher-performance formulations, including a high-purity silver-based high-temperature anti-seize compound (767) and a copper-based anti-bite agent (Cu-a). The product quality of these new formulations is described as competitive with imported counterparts. By 2009, the company expanded its portfolio to include a metal heat treatment protective agent, signaling an emphasis on protective coatings and thermal processing solutions.
The enterprise structure includes a fixed asset base and a team of skilled professionals. The organization reports fixed assets around 50 million yuan and a workforce of 116 employees, including senior engineers and engineers. A dedicated technology development department is responsible for new product development, technology transfer, and addressing customer production challenges, underscoring the company’s emphasis on R&D and process optimization.
In 2003, the company restructured and was established as Tongyu Chemical Co., Ltd. The new entity is located in the southern part of Cangzhou City, near the Bohai Bay, with convenient access to major transportation routes such as the Tianjin-Tianjin–Beijing railway and the Beijing-Fuzhou Expressway.
