Core Viewpoint - Polyimide (PI) is a critical material with exceptional properties, widely used in aerospace, flexible displays, and advanced chips, yet the high-end market is dominated by foreign giants, creating a "bottleneck" issue for domestic industries [2][21]. Summary by Sections 1. Overview of Polyimide - Polyimide (PI) is a polymer characterized by imide rings, known for its excellent thermal stability, withstanding temperatures from -269°C to over 500°C, making it one of the most thermally stable polymers [4][5]. - PI has diverse applications in aerospace, semiconductors, electronics, and flexible displays, categorized into various forms such as films, fibers, foams, and resins [7][8]. 2. Polyimide Industry Chain - The PI industry chain follows a "raw material supply - product manufacturing - application" model, with a unique integration of synthesis and product formation, leading to a tight coupling of industry segments [10]. - The upstream segment includes core monomers and auxiliary materials, with a reliance on imports for high-end monomers [14][15]. - The midstream focuses on manufacturing various PI products, with significant technical barriers and a predominance of domestic production in lower-end products [17][18]. - The downstream applications span electronics, aerospace, and military sectors, with a growing demand driven by technological advancements [23][24]. 3. Polyimide Market Supply and Demand - Global PI production capacity increased from approximately 90,000 tons in 2020 to 110,000 tons by the end of 2023, with a compound annual growth rate (CAGR) of 6.9% [28][30]. - The market for PI materials is projected to reach 104.4 billion yuan by 2030, with a CAGR of 6.98% from 2023 to 2030 [37]. - In China, PI production capacity is expected to grow significantly, with a focus on high-performance products to meet domestic demand [42][46]. 4. Polyimide Process Technology - The production of PI products involves complex chemical reactions and requires a multidisciplinary approach, integrating chemistry, materials science, and mechanical control [55][57]. - Various synthesis methods for PI resins include one-step, two-step, and three-step processes, each with distinct technical requirements [58].
