PEKKis hailed as the culmination of next-generation materials.
It possesses extremely high strength (eight times that of steel), very low weight (only one-third that of aluminum), and excellent heat resistance and chemical stability.12These characteristics make PEEK an ideal material for robotics manufacturing..
The Tesla Optimus second-generation humanoid robot is a typical case of PEEK material application in the robotics field. This robot utilizes a large amount of PEEK material as a lightweight solution, significantly enhancing the robot’s flexibility and motion performance.
PEEK has the following main characteristics:
PEEK has a melting point of 343°C, maintaining extremely high tensile strength, flexural strength, and compressive strength even in high-temperature environments. For example, at 250 degrees Celsius, PEEK’s tensile strength can still exceed 100 MPa..
It can achieve UL standard 94V-0 level even without any flame retardants.
Moreover, it is almost insoluble in any solvents and strong acids or bases, dissolving only in concentrated sulfuric acid, demonstrating extremely high chemical stability..
It is also suitable for various friction environments, reducing friction wear and heat generation, extending the lifespan of components and lowering maintenance costs..
Due to its outstanding performance, it is widely used in various fields:
First: Zhongxin Fluorine Materials (002915)
Zhongxin Fluorine Materials is a leading enterprise in the domestic PEEK core raw material, difluorobenzophenone (DFBP). Zhongxin Fluorine Materials has established a complete production chain from fluorite ore to fluoroketone,DFBP, PEEK to injection molding, forming a unique competitive advantage. This complete industrial chain layout not only enhances the company’s gross profit margin but also solidifies its position in the lightweight materials market.
Second: Juhua Group (301131)
The company has been committed to the research and development of high-end modified composite materials, and has achieved some results in the study of modified PEEK composites, possessing certain technical reserves and obtaining relevant patents.
Third: Xinhang New Materials (301076)
As one of the leading domestic PEEK material enterprises, Xinhang New Materials holds a certain share in the global PEEK market, especially in the domestic market, where its price advantage makes the trend of domestic substitution evident.
Fourth: Zhongyan Co., Ltd. (688716)
The company is the fourth in the world to achieve an annual production capacity of thousands of tons of PEEK, following the UK’s Victrex, Belgium’s Solvay, and Germany’s Evonik, and is the second in the world to use a 5000L reactor for PEEK polymerization production after Victrex, currently being the largest PEEK producer in China.
Fifth: Ocean Biological (003017)
The products produced by the company, such as 4,4-difluorobenzophenone, are crucial intermediates for the production of PEEK materials. This connection allows Ocean Biological to occupy an important position in the PEEK material field and benefit from the growing demand for PEEK materials.
Sixth: Fuheng New Materials (832469)
The company has invited Academician Qian Xigao of the Chinese Academy of Engineering as a consulting expert to collaborate on the development of PEEK series products, which are currently in the small-scale testing stage. In addition, Fuheng New Materials is also focusing on the application of PEEK materials in medical and humanoid robots, aiming to become a leading domestic provider of modified plastic comprehensive services.
