Core Viewpoint - PEEK (Polyether Ether Ketone) is a third-generation high-performance thermoplastic engineering plastic that excels in heat resistance, wear resistance, and corrosion resistance, making it an ideal substitute for metals and ceramics in various demanding applications [2][8]. Group 1: Performance Characteristics - PEEK exhibits outstanding properties such as high temperature resistance (long-term use temperature > 260 °C), self-lubrication (friction coefficient 0.15–0.35), high strength (tensile strength > 150 MPa), and chemical stability (resistant to pH 1–14 corrosion) [2][13]. - Compared to traditional materials, PEEK's comprehensive performance and high product added value position it as a leading choice in specialized engineering plastics [10][14]. Group 2: Synthesis Process - The primary method for synthesizing PEEK is nucleophilic substitution, which allows for precise control over the reaction process, resulting in high purity and structural integrity of the material [3][19]. - The synthesis process requires stringent conditions and high-quality raw materials, leading to higher production costs [22][26]. Group 3: Demand and Applications - PEEK is widely used in various industries, including aerospace, automotive, electronics, and medical fields, due to its lightweight and high-performance characteristics [4][34]. - The demand for PEEK is expected to grow significantly, particularly in robotics, where the estimated demand could reach 10,000 tons, corresponding to a market size of 4 billion yuan if production reaches one million units [4][34]. Group 4: Supply and Market Dynamics - The global PEEK market is dominated by a few key players, including Victrex, Solvay, and Evonik, while domestic companies like Zhongyan Co., Watte Co., and Jinfat Co. are rapidly increasing their production capacity [5][6]. - The supply chain for PEEK's raw materials, such as DFBP and phenol, is primarily concentrated in China, with limited global production capacity [5][24]. Group 5: Future Outlook - The domestic PEEK market is projected to reach 5,078.98 tons by 2027, excluding the robotics sector, indicating a robust growth trajectory [6]. - Innovations in material modification technologies and processing methods, such as 3D printing, are expected to further expand PEEK's applications in various fields [4][34].
