Group 1: Overview of Specialty Nylon - Specialty nylon refers to polyamide materials excluding common nylons (PA6 and PA66), including long-chain nylon, high-temperature nylon, transparent nylon, and bio-based nylon [5][7]. - Long-chain nylon and high-temperature nylon dominate the specialty nylon market, with various subcategories emerging to meet diverse application needs [5][8]. Group 2: Market Supply and Demand - The global specialty nylon production capacity is approximately 600,000 tons per year, with major producers including Arkema, DuPont, and DSM [10][11]. - The market is characterized by high technical barriers in key monomers and polymerization processes, with significant contributions from both international giants and emerging domestic producers [10][14]. Group 3: Long-Chain Nylon - Long-chain nylon, defined by having more than ten methylene groups in its molecular chain, exhibits high toughness and low water absorption, making it suitable for applications in automotive, electronics, and military sectors [16][20]. - The global production capacity for long-chain nylon is around 270,000 tons per year, with a projected market value of $2.846 billion in 2024, expected to grow to $3.64 billion by 2031, reflecting a CAGR of 3.6% [21][23]. Group 4: High-Temperature Nylon - High-temperature nylon can operate at temperatures up to 150°C, with a global production capacity of approximately 335,000 tons per year, widely used in automotive, electronics, and mechanical manufacturing [26][32]. - The production of high-temperature nylon is dominated by companies like DuPont and Solvay, with ongoing innovations in synthesis processes to enhance performance and sustainability [28][32].
