Summary by Sections Introduction - The evolution of engineering plastics, particularly PPO, is linked to significant industrial transformations, akin to the role of steel in the industrial revolution [3]. Overview of PPO - PPO, known for its high production barriers and stringent polymerization processes, is recognized as one of the five major engineering plastics globally [4]. - Its unique molecular structure provides several core physical advantages, including low dielectric loss, excellent thermal stability, and high mechanical strength [7][9][11]. Development History - The commercialization of PPO has evolved through various phases, from initial discovery in the 1950s to the current phase of domestic production breakthroughs in China [12][13]. Classification and Forms of PPO - PPO can be categorized into various types, including pure PPO, modified PPO, and functionalized PPO, each with distinct properties and applications [14][15]. Core Application Scenarios - PPO is extensively used in strategic fields such as new energy vehicles, photovoltaic energy, and aerospace, with its most critical value being in AI servers and data centers due to its low signal loss characteristics [16][17]. Industry Chain Analysis - The PPO industry chain is characterized by high technical and capital intensity, with a clear division from upstream raw materials to downstream applications [20][21]. - The production chain includes the synthesis of the core monomer 2,6-Dimethylphenol, followed by polymerization and modification processes [23][25][29]. Market Analysis - The global PPO market is projected to grow from approximately 22.55 billion yuan in 2023 to nearly 30.68 billion yuan by 2030, with a CAGR of 3.5% [33]. - The Chinese PPO market is also expanding, with a forecasted demand of 245,000 tons by 2030, accounting for 22% of the global market [35]. Supply and Demand Dynamics - The supply side of the PPO market is dominated by a few key players, including SABIC and Asahi Kasei, while domestic production in China is rapidly increasing [39][42]. - Demand drivers include the surge in AI computing needs and the electrification of vehicles, with PPO being essential for high-frequency applications [46][50]. Technical Analysis - PPO's competitive edge lies in its unique molecular structure and the complexity of its polymerization process, which presents significant barriers to entry for new competitors [55][56]. - The modification techniques for PPO are crucial for enhancing its processability and functional properties, enabling its application in high-end markets [59].
