Chan Ye Xin Xi Wang·2025-04-18 01:30Overview - The domestic polyphenylene sulfide (PPS) fiber industry has developed rapidly in recent years, driven by stricter environmental regulations and increasing demand for high-performance materials in various sectors such as automotive, electronics, and aerospace [5][11]. - PPS fibers are ideal for environmental filtration materials due to their high-temperature resistance and chemical corrosion resistance, making them suitable for flue gas treatment in coal-fired power plants, industrial coal-fired boilers, and waste incinerators [11]. - The market demand for PPS fibers is expected to reach 13,638 tons with a market size of 70,507 million yuan in 2024 [11]. Development Background - The rapid development of industries such as automotive and electronics has increased the demand for high-performance materials, which in turn drives the growth of the PPS fiber market [5]. - The rising environmental awareness among consumers has led to a demand for recyclable or biodegradable PPS fiber products, aligning with market needs for sustainable materials [5]. Industry Chain - The upstream of the PPS fiber industry includes key raw materials like PPS resin and production equipment, with several domestic companies such as Zhejiang Xinheng and Shandong Binhua involved in resin production [7]. - The midstream consists of the production of PPS fibers, while the downstream encompasses application markets in environmental protection, textiles, and military industries [7]. Demand Structure - The environmental sector is currently the largest demand market for PPS fibers in China, accounting for over 60% of the market share in 2024 [9]. - Policies promoting carbon reduction and environmental protection are expected to boost the growth of the PPS fiber industry [9]. Competitive Landscape - Major global players in the PPS fiber market include Toray and Celanese, with Japanese companies like Toray leading in production technology and market share [13]. - Domestic companies such as Sichuan Anfeier and Chongqing Pulisheng have made significant advancements in R&D and production capacity, although high-end products still rely on imports [13][14]. Representative Domestic Companies - Sichuan Anfeier focuses on the R&D of PPS materials, with an annual production capacity of 30,000 tons of modified plastics and 10,000 tons of PPS specialty fibers [17]. - Chongqing Pulisheng specializes in the R&D, production, and sales of PPS fibers and has filed numerous patents related to PPS fiber technology [19]. Development Trends - Future trends in the PPS fiber industry include the introduction of nanomaterials and composite materials to enhance key properties such as strength and heat resistance, particularly for high-end applications in aerospace [21]. - The development of low-energy, low-emission production technologies and recyclable or biodegradable PPS fiber products will be crucial to meet environmental standards and market demands [21].
