宝理塑料技术中心所长孙竑：LCP在新能源车中的应用探讨

Core Viewpoint - Liquid Crystal Polymer (LCP) is a new type of polymer material with low viscosity and high orientation in the liquid crystal phase, offering excellent properties such as high strength, high modulus, outstanding heat resistance, low water absorption, excellent flame retardancy, minimal thermal expansion coefficient, and good electrical insulation [2] Group 1: LCP Applications in Automotive Industry - In the automotive industry, the requirements for materials differ between electric vehicles and internal combustion engine vehicles, leading manufacturers to reconsider material choices. LCP is gradually replacing other plastics due to its benefits in thermal management, smaller component production, and suitable electromagnetic interference (EMI) shielding [3] - LCP is used in automotive combustion system components, combustion pumps, thermal insulation parts, precision components, and electronic components. For instance, Keihin, a Honda subsidiary, has integrated a new power control unit (PCU) in Honda's ODYSSEY hybrid vehicle, utilizing Polyplastics' LAPEROS® LCP S135 resin for miniaturization and lightweighting [3] - The LAPEROS LCP material meets high demands for heat resistance, insulation strength, material strength, flowability during molding, and low outgassing, addressing the challenges faced in smart power module housings [3] Group 2: Industry Events and Expert Insights - Sun Hong, the director of the Polyplastics Technical Center, will attend the 2025 Polymer Industry Annual Conference to discuss "LCP Applications in New Energy Vehicles" [4] - The global chemical industry is undergoing significant transformation, with many companies feeling anxious yet hopeful. The rise of emerging industries in China is expected to lead the next decade in polymers [9] - The 2025 Polymer Industry Annual Conference will invite international leading companies, industry experts, and various stakeholders to explore new opportunities in materials, technologies, and equipment across emerging industries such as AI, low-altitude economy, aerospace, and new energy vehicles [9]
