Group 1: Impact of the Crisis on PPS Supply Chain - The crisis has led to fluctuations in international oil prices, causing a "butterfly effect" that increases the costs of raw materials essential for PPS production, thereby raising the prices of PPS products [5]. - Japan's dominance in the PPS market poses a risk due to its heavy reliance on Middle Eastern oil imports, with approximately 90% of its oil coming from this region, making it vulnerable to supply disruptions [7][12]. - The logistics and delivery chains for PPS are severely affected, as Japanese suppliers are key to the global automotive and electronics supply chains, leading to potential production halts for domestic manufacturers relying on just-in-time (JIT) inventory systems [9][10]. Group 2: Domestic PPS Alternatives - The crisis has catalyzed the development of domestic PPS alternatives, as Chinese manufacturers have begun to establish a complete PPS modification industry chain, reducing reliance on imports [11]. - China's energy supply is diversified, with alternative sources such as land pipelines from Russia and Central Asia, as well as coal-to-chemicals processes, providing a buffer against oil supply disruptions [11][12]. - Domestic PPS manufacturers are increasingly capable of meeting the high-performance requirements of industries such as electric vehicles and air filtration, with several companies emerging as viable alternatives to Japanese suppliers [13][14]. Group 3: Key Domestic Players - Jinfa Technology is noted for its large-scale production capabilities in general-purpose PPS, successfully supplying major domestic manufacturers during import disruptions [14]. - Water Holdings has made significant strides in the high-frequency communication sector with its low-dielectric PPS materials, breaking the foreign monopoly in this niche market [15]. - KCC Corporation has adopted a customized approach to meet specific application needs, successfully replacing Japanese materials in demanding environments such as electric vehicle thermal management systems [16][20]. Group 4: Selection Criteria for PPS Materials - For general-purpose and structural components, manufacturers should prioritize suppliers with robust supply capabilities, such as Jinfa Technology, focusing on their production capacity and historical delivery reliability [19]. - In high-performance applications, companies like Water Holdings should be considered for their specialized products that meet stringent technical requirements [19]. - For complex and precision components, the focus should be on suppliers like KCC Corporation that offer tailored solutions and have strong collaborative development capabilities [20].
