DT新材料·2025-08-18 16:05Core Viewpoint - The article emphasizes the growing importance of nylon in the automotive industry, particularly in the context of lightweighting and performance enhancement for components such as cooling systems and fuel lines. The domestic production of nylon 66 is expected to surge, with a projected capacity exceeding 8 million tons by 2025, positioning nylon as a critical material for new energy vehicles [2]. Industry Overview - Nylon is widely used in automotive applications due to its advantages such as vibration fatigue resistance, fuel resistance, heat resistance, and low roughness, accounting for approximately 20% of the total plastic used in vehicles [2]. - The shift from traditional rubber hoses to nylon can lead to weight reductions of over 50%, which is particularly beneficial for electric vehicles where weight plays a crucial role in efficiency [2]. - The design and quality of nylon piping directly impact the overall technical level of vehicles, especially in cooling systems for new energy vehicles [2]. Market Development - The domestic nylon 66 production capacity is expected to experience significant growth, with plans to exceed 8 million tons by 2025, driven by breakthroughs in the domestic production of hexamethylenediamine [2]. - The increasing competition in the market has made nylon a key application area for new energy vehicles, highlighting its strategic importance in the automotive supply chain [2]. Event Participation - Hu Fa, Deputy Director of the Pipe and Fitting Testing Room at Sinopec (Beijing) Chemical Research Institute, will present on "Automotive Nylon Pipeline Technology Development and Application" at the 2025 Polymer Industry Annual Conference [3].
