- Policy Winds Fill the Sails, Domestic Capacity Expands Rapidly
Following its initial development by Imperial Chemical Industries (ICI) of the UK in 1978, PEEK technology was long monopolized by a handful of foreign corporations, leaving China’s market dependent on imports. This landscape has fundamentally shifted. Guided by national strategies and supported by sustained research and enterprise endeavors, China’s PEEK industrialization process has markedly accelerated. “With its vast application prospects and strong growth potential, PEEK has become a core focus area for capital markets, and the industry is ushering in an unprecedented golden period of opportunity,” stated Zhang Sidai, Member of the Party Committee and Deputy General Manager of China Chemical Industry News Co., Ltd.
Policy directives have been unequivocal. The proposal for the “15th Five-Year Plan” adopted by the Fourth Plenary Session of the 20th Central Committee explicitly calls for “accelerating the development of strategic emerging industrial clusters such as new energy, new materials, aerospace, and the low-altitude economy,” charting a clear course for the petrochemical and high-performance materials sectors. Furthermore, PEEK has been consistently listed in the Ministry of Industry and Information Technology’s *Catalogue of Key New Materials for First Application Demonstration* (2017, 2019, and 2021 editions). The outline for the “14th Five-Year Plan” and the Long-Range Objectives Through 2035 also emphasizes fostering pioneering and pillar industries to seize future development opportunities, targeting a contribution of strategic emerging industries to GDP exceeding 17%.
Spurred by these policies, domestic enterprises have significantly increased investment in the PEEK industry. This has led to a substantial rise in production capacity and output, with the domestic production rate climbing steadily, presenting a vibrant development outlook. It is projected that by 2025, China’s PEEK industry will have completed a leap from “import dependence” to “technological leadership.”
- Market Dynamics: Reshaped Supply and Soaring Domestic Demand
On the global stage, PEEK supply remains relatively concentrated. According to Yang Yitao, Chief Analyst of the chemical industry at Guosheng Securities, global PEEK capacity stands at approximately 15,000 tons. Three foreign firms dominate about 65% of this capacity: UK-based Victrex has a nominal capacity of 9,500 tons (8,000 tons in the UK, 1,500 tons in China), Belgium’s Solvay holds 2,500 tons, and Germany’s Evonik has 1,800 tons (with actual capacity around 70% of nominal). In China, capacity is primarily concentrated in a few companies like Zhongyan Plastics, and current under-construction capacity has already surpassed 6,000 tons.

| Evonik (Germany) | 1,800 | Actual capacity ~70% of nominal |
| Chinese Domestic (e.g., Zhongyan) | Significant expansion | Capacity under construction >6,000 tons |
Demand in China is skyrocketing. Data from LeadLeo Research Institute shows that from 2019 to 2022, the compound annual growth rate (CAGR) of PEEK demand in China reached 18.57%, far outpacing the global consumption growth rate of 9.00%. China’s market growth was approximately double the global average. According to Frost & Sullivan projections, China’s PEEK demand is expected to continue growing at a CAGR of 16.82% from 2022 to 2027, reaching a scale of 5,079 tons by 2027.
Globally, PEEK consumption is concentrated in Europe, the Americas, and the Asia-Pacific region, with Europe being the largest and most mature market. However, as global production capacity for electronics, automobiles, and aerospace continues to shift to the Asia-Pacific region, PEEK consumption growth there, especially in China, is surging. Emerging markets like China, India, and Southeast Asia are poised to become the primary drivers of global PEEK demand growth in the coming years.
- Penetration Across Scenarios: Humanoid Robotics and Beyond
The recent explosion of interest in humanoid robotics, exemplified by companies like Unitree Robotics, has accelerated related industrial chain deployments. Numerous firms are racing to lay out their stakes in PEEK materials and components.
Fuchun Dyeing & Weaving recently indicated it has established comprehensive technical reserves and sampling channels for lightweight PEEK components in humanoid robots and has received a sample order from a humanoid robot planetary reducer company. Ningbo Huaxiang stated it is currently developing related core parts for intelligent robots based on PEEK material and has made phased progress. Lianhe New Materials also confirmed it has completed PEEK-related technology development and pilot-scale production, advancing towards industrialization. Its PEEK products can serve as materials for bearings, gears, limb skeletons, and other parts in humanoid robots.
The material requirements for humanoid robots—lightweight, durability, and precision—align perfectly with PEEK’s properties. As Yang Yitao explains, the push for lightweighting stems from two main factors: reducing weight lowers energy consumption and extends operational duration, and a lighter robot poses less safety risk to users if it falls. PEEK’s low density and high specific strength, further enhanced by carbon fiber composite modification, make it an ideal material for structural components like limb skeletons and exoskeletons, maintaining strength while reducing weight.
Analysts peg 2025 as the inaugural year for mass production of humanoid robots, with domestic shipments expected in the tens of thousands and overseas leading manufacturers shipping in the thousands. Research from Guojin Securities suggests that for every 100,000 robots designed with composite materials, 195 tons of PEEK material would be required. Given the promising demand outlook for humanoid robotics, PEEK application potential is significant, positioning China robot advancements as a new major growth driver for the PEEK industry.
Simultaneously, PEEK’s value is becoming increasingly evident in the low-altitude economy, a strategic emerging industry seen as vital for cultivating new quality productive forces. Forecasts from the Civil Aviation Administration of China predict the low-altitude economy will reach a market size of 1.5 trillion yuan by 2025 and 3.5 trillion yuan by 2035. PEEK, as a crucial material in this sector, is poised for rapid development.
In aerospace, where demands for lightweight, high-temperature resistance, corrosion resistance, and mechanical performance are extreme, PEEK is an excellent fit. Current applications include wheel hub covers, fairings, environmental control system impellers, connector cables, conduits, and UAV components. It serves as a lightweight metal replacement, reducing aircraft weight to improve economics and performance while offering resistance to extreme temperatures and flammability.
Overall, due to its outstanding comprehensive properties in strength, dielectric constant, and chemical resistance, PEEK enjoys broad market prospects under the downstream trends of “plastic replacing steel” and “lightweighting.” Beyond China robot and aerospace sectors, PEEK finds wide applications in new energy vehicles, electronic and electrical devices, and medical equipment. As emerging industries evolve and technology progresses, its application fields will further widen, ensuring sustained market growth.
- Technology Deep Dive and Industrial Chain Challenges
Despite remarkable achievements in localization, technological innovation, and application expansion, China’s PEEK industry still faces multiple challenges: securing core raw material supply, breaking through high-end composite material technology barriers, managing long capacity ramp-up cycles, and controlling costs. The future requires a focus on raw material autonomy, process optimization, breakthroughs in composite modification technology, stabilizing supply, perfecting industrial chain support, and continuously enhancing product competitiveness and market adaptability.
“The PEEK industry’s capacity ramp-up cycle is relatively lengthy, necessitating early planning for capacity layout,” noted Yang Yitao. During this process, temporary imbalances between market supply and demand may occur. However, from a long-term perspective, the continuous expansion of downstream applications and the gradual release of market demand will ultimately drive steady growth in the overall industry scale.
Raw material supply is foundational. Core materials include difluorobenzophenone (DFBP) and hydroquinone, with DFBP accounting for over 50% of PEEK production costs. Its quality directly affects PEEK’s crystallinity and mechanical performance. Some domestic companies have made significant breakthroughs. For instance, Xinhan New Material’s DFBP production line domestically pioneered the use of the Friedel-Crafts acylation process, implementing systematic innovations around it. According to Li Xiangfei, Board Secretary of Xinhan New Material, this process yields high product recovery rates and exceptional purity (above 99.9%), and is now stably supplying PEEK industry giants.
Regarding hydroquinone, Zhou Zhongping, Director and Senior Vice President of Brother Science & Technology Co., Ltd., explained that impurity control is key, directly impacting PEEK synthesis. Among synthesis routes, the phenol hydroxylation method produces fewer byproducts, offers the most competitive comprehensive manufacturing cost, is a greener process, and is viewed as the future mainstream production method.
Technologically, the nucleophilic substitution route remains dominant for PEEK synthesis. This path allows precise control over the reaction process and molecular structure, resulting in materials with high regularity, ordered molecular chains, excellent performance stability, and high purity suitable for demanding applications. However, the stringent reaction conditions and relatively high raw material costs make this an expensive production method.
The development of PEEK composites is a key industry focus. Composite modification with various reinforcing materials can further amplify PEEK’s performance advantages for more苛刻 applications. Carbon Fiber Reinforced PEEK (CF/PEEK) is currently one of the most watched core categories. CF/PEEK combines the high strength of carbon fiber with the excellent chemical stability of PEEK, offering superior prospects in aerospace and high-end equipment manufacturing compared to single materials.
Guojin Securities believes CF/PEEK is likely to penetrate critical joints of China robot bodies first, addressing plastic brittleness while achieving lightweighting. According to a report from New Silk Road Industrial Research Center, aerospace is the largest demand segment for CF/PEEK, as it maintains dimensional stability in high-temperature environments, making it suitable for UAV engine components, propellers, and frames.
Currently, CF/PEEK production technology is mastered by a few companies like Toray (Japan) and Victrex (UK). Domestic R&D is concentrated in universities, research institutes, and a handful of enterprises, limiting widespread application. Pioneering domestic firms like Zhongyan Plastics, Junhua Shares, and Kent Co., Ltd., are attempting to break these technical barriers. Zhongyan’s carbon fiber reinforced granules are used in automotive functional parts, chemical processing equipment, and mechanical components. Junhua’s continuous CF/PEEK成型 process produces high-performance products for aerospace, medical devices, and petrochemicals. Kent Co., Ltd., has also revealed relevant technical reserves in CF/PEEK.
In summary, China’s PEEK industry has entered a critical phase transitioning from “quantitative breakthrough” to “qualitative leap.” Capacity expansion is merely the first half; the second half’s competition will hinge more on technological depth, application breadth, and cost precision. From purifying key monomers to mass-producing high-end composites like CF/PEEK, and reducing costs to tap into broader markets, each step presents a test for the industry’s long-term trajectory.
The next phase of high-quality development relies on sustained innovation investment and tight industrial chain collaboration. Only by breaking down technical barriers one by one and continuously broadening application scenarios can China’s PEEK industry not only achieve self-sufficiency but also secure a place in the global competition for high-end materials, truly becoming a cornerstone supporting the development of strategic emerging industries, including the rapidly evolving China robot ecosystem.
