We cordially invite you to attend SAMPE China 2026, the 21st International Exhibition on Advanced Composite Materials and Engineering Applications, to be held from June 10–12, 2026, at the China International Exhibition Center (Chaoyang Hall) in Beijing.

Company Profile

Zhongke Jinding (Beijing) New Materials Co., Ltd. is a high-tech enterprise specializing in the research, development, production, and sales of polybenzimidazole (PBI). PBI is currently one of the highest‑grade high‑temperature‑resistant materials in the world, boasting exceptional thermal stability, mechanical properties, and chemical resistance. Owing to its outstanding characteristics—such as superior heat resistance, flame retardancy, radiation resistance, electrical insulation, strong adhesion, and excellent mechanical strength—PBI is widely employed as a core material across numerous fields, including aerospace, defense, nuclear energy, hydrogen‑powered vehicles, energy storage, next‑generation electronic connectors, fire protection, and protective apparel.

The company’s principal products are PBI high-performance materials, categorized into five major types: resins, solutions, proton exchange membranes, profiles, and fibers. Based on solubility, they are classified as soluble or insoluble resins; according to processing characteristics, they are divided into thermoplastic and thermosetting resins; and depending on their application in proton exchange membranes, they include series such as fuel cell membranes and energy‑storage membranes. Profiles are further available in forms like sheets and rods. Currently, the company has established a product portfolio comprising 26 grades and specifications, suitable for processing methods including injection molding, extrusion, compression molding, spray coating, film formation, and fiber drawing, thereby meeting downstream customers’ diverse application requirements for PBI.

The company has achieved numerous innovations and breakthroughs in the theory and technology of PBI synthesis, purification, and composite reinforcement, mastering end-to-end domestically produced PBI manufacturing capabilities that encompass critical raw-material selection, key process control, specialized equipment design, optimized processing routes, and rigorous monitoring of performance indicators. In the realm of large-scale industrial production, it has become the second enterprise worldwide—after the U.S.-based PBI company—to attain an annual PBI production capacity on the order of 100 tons. By overcoming domestic technological bottlenecks in specialty high‑temperature‑resistant materials, the company continues to drive import substitution in the Chinese market.
