In today’s rapidly developing new energy vehicle industry, battery life has always been the focus of users. Industry consensus shows that for every 10% weight reduction of the vehicle, the battery life can be increased by 6%-8%. This key indicator is driving engineering plastics such as PC/ABS alloys to become the core material for lightweight vehicles. Through continuous technological innovation, domestic engineering plastic brands have continuously achieved breakthroughs in the high temperature resistance, structural strength and environmental performance of materials.
For example, a leading domestic automotive parts supplier uses high-performance PC/ABS alloy materials to create interior parts (such as seat backs, armrests, etc.) for mid-to-high-end models. This type of material not only meets the stringent automotive industry standards, but also has the significant characteristics of low emissions and high fluidity, which can effectively improve the production efficiency of thin-wall injection molding processes.
Battery pack shells are another key application scenario for PC alloy materials. PC composite materials using flame retardant modification (UL94 V-0 certified) and long fiber synergistic reinforcement technology can significantly improve the impact strength of battery shells. Research shows that the optimization range is considerable, and the air tightness of the material has also been significantly improved, effectively solving the sealing risks that electric vehicle batteries may face under bumpy road conditions. In the field of charging piles, halogen-free flame-retardant PC alloy materials with excellent weather resistance, insulation and low-temperature impact resistance have become an ideal choice for shell manufacturing due to their excellent comprehensive performance, and are widely used in outdoor charging equipment.
Lightweighting of car windows is a major breakthrough in domestic material technology. Through innovative hot pressing mold technology, the development cycle of front-hardened PC glass has been greatly shortened, the cost has been significantly reduced, and the production restrictions of traditional processes on large-size PC glass have been successfully broken through. This technology has been successfully applied to the rear windshields and other components of many new energy vehicle models. According to industry research institutions, by 2025, the proportion of automotive PC alloy materials in automotive lightweight materials will increase significantly, and the market share of domestic materials will also achieve strong growth.
In the future, with the popularization of autonomous driving technology, the integrated design of light-transmitting PC film and sensors (such as hidden radar heating film technology used in some high-end models) is expected to become the next important growth point for the development of domestic high-performance materials.
