Dalian JiangYu New Material Science and Technology Co., Ltd

The company has obtained ISO9001 quality management system certification and security system certification. We are a National High-Tech Enterprise and a Liaoning Provincial "Specialized and Sophisticated" SME. Since our founding, we have been granted 17 patents, demonstrating strong technical capabilities and innovation strength that have been widely recognized by the industry.

In 2024, the project “Key Technologies and Applications of High-Temperature Poly(ether nitrile imide) Resins and Their Composites,” led by Professor Chen Ping from Dalian University of Technology and co-developed by our Deputy General Manager Sun Youjun, won the Second Prize of the Liaoning Provincial Science and Technology Award for Technological Invention. In December 2024, the company was invited to participate in the COMAC (Commercial Aircraft Corporation of China) Northeast Regional Scale-Up Launch Conference, positioning us as a potential PEEK new material supplier.

We have an outstanding team of experts and strong R&D capabilities. Our product development strategy emphasizes independent innovation, supplemented by introduction, absorption, and collaboration. We adhere to the product development approach of "production, R&D, and planning — with annual planning," forming a comprehensive, multi-level technology development framework centered on the R&D of new functional material specialties.

The company now operates multiple production lines covering compounding, injection molding, compression molding, extrusion, machining, and composite forming, establishing comprehensive processing and forming capabilities. Our products include PEEK injection-molded parts, machined compression-molded parts, profiles (sheets, rods, tubes), films, fibers, heat-shrinkable tubing, and composite special-shaped products. These are widely used in aerospace, electronics, petrochemical, new energy vehicles, rail transportation, medical devices, and pump/valve components.

After more than a decade of dedication, we have achieved full domestic industrial chain integration for PEEK materials — from raw materials to finished products — realizing a complete "material–product–component–application" value chain.

PEEK Films: After two years of intensive R&D, the company produced PEEK films in January 2023 that rival imported alternatives, making us one of only two domestic companies capable of meeting this standard. To date, we have launched six full-series grades of high-end PEEK films, including acoustic films, frosted films, insulating films, and anti-static films, achieving eight key technological breakthroughs across three major categories. Our self-developed PEEK film production lines, with an equipment cost of just 500,000 to 1 million RMB per line, achieve the same ±0.003 precision standard as imported equipment priced at 16 million RMB.

PEEK Cotton and PEEK Fabric: We successfully overcame the industrial production challenges of PEEK cotton and fabric, transforming rigid PEEK blocks into flexible textiles — filling a technical gap in the domestic industry.

Our products offer outstanding heat resistance, flame retardancy, wear resistance, high strength, chemical resistance, excellent processability, and radiation resistance. They are increasingly used in aerospace, electrical and electronic engineering, petrochemical, new energy vehicles, rail transportation, medical devices, and general machinery manufacturing.

After more than a decade of focus and innovation, Dalian Jiangyu New Material Technology Co., Ltd. has grown from a startup into a leading force in China's domestic PEEK new materials industry. We will continue to uphold the philosophy of "innovation, development, integrity, and win-win cooperation," driving sustainable growth through technology and innovation, and striving to become a competitive and recognized brand in the new materials field.
