Zhongke Jinding (Beijing) New Materials Co., Ltd. is a high-tech enterprise specializing in the research, development, production, and sales of polybenzimidazole (PBI).
The company’s principal products comprise PBI high-performance materials in five major categories: resins, solutions, proton exchange membranes, fibers, and profiles. Based on solubility, these are further classified into soluble and insoluble resins; according to their applications as proton exchange membranes, they are divided into ten product series, including fuel cell membranes and energy storage membranes. Currently, the company has established a product portfolio consisting of 26 distinct grades across five categories and ten series, suitable for processing methods such as compression molding, spray coating, film formation, and fiber drawing, thereby meeting the diverse application requirements of downstream customers.
Through continuous independent R&D, the company has achieved numerous innovations and breakthroughs in the theory and technology of PBI synthesis, purification, and composite reinforcement. It has mastered a fully domestically produced, end-to-end PBI manufacturing capability—covering critical raw-material selection, key process control, specialized equipment design, optimized processing routes, and rigorous monitoring of performance indicators—thereby addressing longstanding domestic gaps. In large-scale industrial production, the company’s PBI manufacturing technology is on par with international standards, making it only the second enterprise worldwide to reach an annual production capacity of over 100 tons. By overcoming critical technological bottlenecks that have long constrained China’s supply of specialty high‑temperature materials, the company has steadily replaced imported alternatives in the domestic market and is gradually breaking the decades‑long monopoly held by European and American firms in global markets. Leveraging stable product performance and a strong cost‑effectiveness advantage, it is expanding into major global regions such as North America, Europe, and the Asia‑Pacific, with its products now exported to the United States, Singapore, Switzerland, Denmark, and many other countries and territories, earning widespread recognition from international downstream customers.

Leveraging its technological advantages in end-to-end domestic production, the company’s products are widely deployed in high‑end sectors such as aerospace, petrochemicals, semiconductor manufacturing, new‑energy hydrogen, and specialized protective applications. They are suitable for critical applications including spacecraft thermal protection systems, high‑temperature proton exchange membranes for fuel cells, semiconductor component packaging, and advanced flame‑retardant protective garments, meeting the demanding requirements of extreme environments. By doing so, the company supports technological upgrades and industrial transformation across downstream industries, fulfilling its strategic mission of advancing the localization of specialty new materials.
As a leading enterprise in China’s PBI industry, the company has consistently placed technological innovation at the heart of its growth strategy. It continues to ramp up R&D investment, deeply cultivating performance optimization and application expansion for PBI materials, while steadily overcoming technical challenges such as high-purity monomer synthesis and advanced polymerization process upgrades. These efforts have helped narrow the gap with international best-in-class standards, driving product development toward higher-end, more refined, and diversified offerings. At the same time, the company has established a comprehensive pre-sales, in-sales, and after-sales service system, providing tailored solutions to global customers and seamlessly integrating product supply with technical support, thereby progressively expanding its market share and influence in the global PBI sector.
Looking ahead, Zhongke Jinding will remain committed to the path of independent innovation, deepen industry–university–research collaboration, and refine its PBI industry‑chain strategy. The company will continue to strengthen its domestic market position while accelerating its international expansion, striving to become a global leader in the high‑performance PBI materials sector. In doing so, it will make a pivotal contribution to the high‑quality development of China’s advanced new‑materials industry, help break international technology blockades, and ensure the security of industrial and supply chains, thereby supporting the upgrading and advancement of the global high‑end manufacturing sector.
