中化国际，芳纶成功应用于电池箱体

Core Viewpoint - The successful application of Sinapara® aramid materials by Sinochem International in a new battery box product marks a significant breakthrough in the context of the upcoming national standards for electric vehicle power batteries [1][2]. Group 1: National Standards and Safety Requirements - The new mandatory national standard "Safety Requirements for Power Batteries for Electric Vehicles" (GB 38031—2025) will be implemented starting July 2026, significantly raising safety thresholds compared to the 2020 version, with additional testing requirements for battery box materials, structural design, and engineering processes [2]. - The Coleitec SafePackTM product features a "sandwich structure" technology protection system, enhancing the safety performance of the battery pack through multi-material collaboration, capable of withstanding impacts of 500 to 1200 joules, exceeding national standards by 3 to 8 times [3]. Group 2: Product Features and Benefits - Sinapara® aramid materials not only provide excellent safety performance but also contribute to a weight reduction of 20% to 30% compared to traditional pure metal battery boxes, optimizing overall vehicle energy consumption [4]. - The Sinapara® aramid long fiber products have undergone life cycle assessment (LCA) and carbon footprint verification, enabling clients to meet higher energy consumption and environmental standards [5].
